Product details
Overview
TPS62410DRCRG4 from Texas Instruments is a synchronous dual step-down DC–DC converter delivering two independent 800-mA output rails with 2.25-MHz fixed-frequency PWM or automatic power-save (PFM) operation. It accepts 2.5 V to 6 V input-compatible with single-cell Li-Ion or 3.3 V/5 V rails-and supports dynamic voltage scaling via EasyScale™ one-pin serial interface. Used in OMAP™ and low-power DSP supply rails, it enables compact, high-efficiency power management in space-constrained portable systems.
For engineers reviewing the TPS62410DRCRG4 datasheet, TPS62410DRCRG4 pinout, TPS62410DRCRG4 application, or TPS62410DRCRG4 equivalent, key selection considerations include dual 800-mA output capability, 180° out-of-phase switching for reduced input ripple, ±1% output voltage accuracy in PWM mode, 32-μA typical quiescent current for both converters, and support for adjustable outputs from 0.6 V to VIN using external resistor networks on DEF_1 and ADJ2 pins.
Technical Context
The TPS62410DRCRG4 integrates two fully independent synchronous buck regulators sharing only the VIN and GND connections. Each employs a fast-response voltage-mode controller with input-voltage feed-forward, enabling stable regulation with small ceramic capacitors. Converter 1 uses DEF_1 as an analog input for external resistor-based voltage setting (0.6 V to VIN), while Converter 2 uses ADJ2 with optional 33-pF feed-forward capacitor or direct VOUT2 connection when using EasyScale™.
Operation includes automatic transition between 2.25-MHz PWM (moderate/heavy load) and pulse-frequency modulation (PFM) at light loads-enabled by MODE/DATA = 0-with dynamic voltage positioning (1% over-regulation in PFM) to minimize load transient undershoot. The 180° phase shift between SW1 and SW2 reduces input RMS current, and thermal shutdown triggers at 150°C with 20°C hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 2.5 V to 6 V - supports single-cell Li-Ion (2.7–4.2 V), 3.3 V or 5 V rails without external LDO pre-regulation |
| Output Current | 2 × 800 mA - each channel delivers up to 800 mA continuously, enabling dual-core processor core and I/O rail powering |
| Switching Frequency | 2.25 MHz (fixed) - allows use of small 2.2 μH inductors and 22 μF ceramic output capacitors for minimal board area |
| Output Voltage Range | 0.6 V to VIN - adjustable per channel via external resistive dividers on DEF_1 and ADJ2 pins |
| Quiescent Current | 32 μA (both converters, PFM mode) - extends battery life in always-on subsystems like real-time clocks or sensor hubs |
| Efficiency Peak | Up to 95% - achieved at mid-load (e.g., 200–600 mA) with 3.6 VIN/1.8 VOUT, critical for thermal management in sealed enclosures |
| Accuracy (PWM) | ±1% - ensures reliable logic-level compliance for 1.2 V, 1.5 V, or 1.8 V digital supply domains |
| Shutdown Current | 1.2 μA - enables deep-sleep states with negligible battery drain during system idle |
Pinout & Package
TPS62410DRCRG4 is housed in a thermally enhanced 10-pin VSON package (3.00 mm × 3.00 mm) with exposed PowerPAD™ for improved heat dissipation. The package supports reflow soldering and achieves RθJA = 45.9°C/W under standard JEDEC conditions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ADJ2 (Pin 1) | Converter 2 feedback adjust | Analog input for external resistor divider to set VOUT2 (0.6 V to VIN); must connect directly to VOUT2 if using EasyScale™ |
| MODE/DATA (Pin 2) | Mode control / serial interface | Low = auto PFM/PWM; High = forced PWM; also serves as open-drain acknowledge line for EasyScale™ voltage updates |
| VIN (Pin 3) | Main power input | 2.5–6 V supply for both converters; requires 10-μF ceramic input capacitor close to pin |
| FB1 (Pin 4) | Converter 1 feedback sense | Direct connection to VOUT1 required; internal reference is 600 mV; no external divider needed for fixed versions |
| DEF_1 (Pin 5) | Converter 1 default voltage select | Analog input for external resistor network to program VOUT1; not used in fixed-output variants |
| SW1 (Pin 6) | Converter 1 high-side switch node | Connects to 2.2 μH inductor; requires low-ESR ceramic output capacitor (22 μF typical) on VOUT1 |
| EN1 (Pin 7) | Converter 1 enable | Active-high digital input; controls soft-start and shutdown independently of EN2 |
| GND (Pin 8) | Power and signal ground | Must be connected to PCB ground plane; PowerPAD™ underneath device is electrically tied to this pin |
| EN2 (Pin 9) | Converter 2 enable | Active-high digital input; enables/disables Converter 2 independently; supports staggered startup sequencing |
| SW2 (Pin 10) | Converter 2 high-side switch node | Connects to second 2.2 μH inductor; 180° phase shift vs. SW1 reduces input ripple current magnitude |
Key Features
| Feature | Design Value |
|---|---|
| 180° out-of-phase switching | Reduces peak input current by ~30% and lowers RMS input ripple, permitting smaller input bulk capacitance |
| Dynamic voltage positioning | Maintains VOUT 1% above nominal in PFM mode to suppress undershoot during sudden load steps (e.g., CPU wake-up) |
| EasyScale™ one-pin interface | Enables real-time adjustment of both output voltages without additional GPIOs or I²C lines-ideal for DVFS in application processors |
| 100% duty cycle operation | Extends usable battery range down to VOUT + IOUT×(RDS(on) + RL) - e.g., sustains 1.5 V output even as Li-Ion drops to ~2.0 V |
| Thermal shutdown with hysteresis | Shuts down at 150°C junction temperature and resumes at 130°C, preventing thermal runaway during sustained 800-mA loads |
| Independent enable control | EN1 and EN2 allow sequenced power-up/down of core and I/O rails-critical for meeting ASIC power sequencing requirements |
Applications
| Smartphone Application Processor Core Rail | OMAP™ DSP Dual-Rail Supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-step-down converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62400DRCR | Same 10-pin VSON package and pinout; lower 1.5-MHz switching frequency; max 600-mA per channel; no EasyScale™ interface | Suitable for cost-sensitive, lower-current applications where dynamic voltage scaling is unnecessary | Select TPS62400DRCR only if output current ≤600 mA/channel and fixed-voltage operation suffices |
| TPS62420DRCR | Identical pinout and feature set; differs only in factory-programmed default output voltages (1.2 V / 1.8 V vs. TPS62410's adjustable defaults) | Used where fixed dual-rail outputs eliminate need for external resistor networks and simplify BOM | Choose TPS62420DRCR when standardized 1.2 V/1.8 V rails are acceptable and design flexibility is secondary to layout reuse |
Compared with TPS62400DRCR, the TPS62410DRCRG4 delivers higher per-channel current (800 mA vs. 600 mA) and adds EasyScale™ for runtime voltage adjustment-critical for adaptive processing. Against TPS62420DRCR, it trades factory-fixed outputs for full external adjustability via DEF_1 and ADJ2, increasing design flexibility at the cost of two extra resistors per channel.

FAQ
What is the maximum continuous output current per channel for the TPS62410DRCRG4?
The TPS62410DRCRG4 supports up to 800 mA continuous output current on each of its two independent buck channels under recommended operating conditions (TA ≤ 85°C, proper PCB thermal design). This rating assumes use of 2.2 μH inductors, 22 μF ceramic output capacitors, and adequate copper pour on the PowerPAD™ thermal pad. Derating applies above 85°C ambient or with insufficient board cooling.
Does the TPS62410DRCRG4 support dynamic voltage scaling, and how is it implemented?
Yes, the TPS62410DRCRG4 supports dynamic voltage scaling via its EasyScale™ one-pin serial interface on the MODE/DATA pin. By sending specific pulse-width-encoded commands, a host microcontroller can adjust both VOUT1 and VOUT2 in real time without additional communication lines. The interface operates with open-drain acknowledge signaling and requires no external pull-up if the host provides one-enabling DVFS for application processors while minimizing GPIO usage.
What is the purpose of the 180° phase shift between the two switching nodes (SW1 and SW2) in the TPS62410DRCRG4?
The 180° phase shift between SW1 and SW2 in the TPS62410DRCRG4 reduces input current ripple amplitude by canceling harmonic components. This allows designers to use smaller input bulk capacitance-typically 10 μF instead of 22 μF-while maintaining equivalent RMS input current stress. The result is lower EMI, reduced capacitor size/cost, and improved efficiency in battery-powered portable systems where board space is constrained.
Can the TPS62410DRCRG4 operate with a single 3.3 V input to generate 1.5 V and 1.8 V outputs?
Yes, the TPS62410DRCRG4 is fully specified to operate from a 3.3 V input to generate 1.5 V and 1.8 V outputs. Its 2.5 V to 6 V input range accommodates standard 3.3 V rails, and its 100% duty-cycle capability ensures regulation even as input sags near dropout. With 2.2 μH inductors and 22 μF ceramic output caps, typical efficiency exceeds 92% at 500 mA per channel under these conditions-validated in TI's SLVS737A datasheet Figure 20.
How does the power-save mode (PFM) function in the TPS62410DRCRG4, and when is it activated?
The TPS62410DRCRG4 enters power-save mode automatically when the MODE/DATA pin is held low and load current drops below a threshold determined by input voltage (e.g., ~30 mA at 3.6 VIN). In PFM mode, switching frequency decreases, quiescent current drops to 32 μA (both channels), and output voltage is positioned 1% above nominal to improve transient response. The device transitions seamlessly back to PWM mode when load increases-no external intervention required.
