Product details
Overview
TPS62410DRCTG4 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 and automatic power-save mode (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-wire interface. Used in OMAP™ processor core/logic supplies and portable media players for efficient multi-rail power management.
For engineers reviewing the TPS62410DRCTG4 datasheet, TPS62410DRCTG4 pinout, TPS62410DRCTG4 application, or TPS62410DRCTG4 equivalent, key selection criteria include dual 800-mA output capability, 180° out-of-phase switching for reduced input ripple, ±1% output voltage accuracy in PWM mode, 32-μA 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 TPS62410DRCTG4 integrates two fully independent synchronous buck regulators sharing only VIN, GND, and MODE/DATA control. Each employs a voltage-mode controller with input-voltage feed-forward, enabling stable regulation with small ceramic capacitors and fast transient response. Converter 1 uses DEF_1 as analog input for output setting; Converter 2 uses ADJ2 with optional 33-pF feed-forward capacitor.
Operation includes three distinct modes: automatic PFM/PWM transition at light loads (MODE/DATA = 0), forced fixed-frequency PWM across full load range (MODE/DATA = 1), and shutdown (EN1 = EN2 = 0). The 180° phase shift between SW1 and SW2 reduces input RMS current by up to 30%, while thermal shutdown (150°C) and undervoltage lockout (1.5 V typical) provide robust protection.
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, and 5 V system rails without external LDO pre-regulation. |
| Output Current | 2 × 800 mA - sufficient to power dual-core processors or baseband + application processor subsystems. |
| Switching Frequency | 2.25 MHz (±12.5%) - enables use of compact 2.2 μH inductors and low-ESR ceramic capacitors for space-constrained designs. |
| Output Voltage Accuracy | ±1% in PWM mode - ensures tight regulation for sensitive digital logic and memory interfaces. |
| Quiescent Current | 32 μA (both converters, PFM mode) - extends battery life in always-on standby states of smartphones and PDAs. |
| Efficiency Peak | 95% - achieved at mid-load (e.g., 300 mA @ 1.8 V out, 3.6 V in), minimizing thermal dissipation in sealed handheld enclosures. |
| Shutdown Current | 1.2 μA - reduces system-level leakage during deep sleep, critical for multi-day battery runtime. |
Pinout & Package
TPS62410DRCTG4 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 is RoHS-compliant and optimized for high-density PCB layouts with minimal footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ADJ2 | Converter 2 output voltage programming input | Analog feedback node for adjustable VOUT2; requires external resistor divider to set 0.6 V–VIN range or direct connection to VOUT2 when using EasyScale™. |
| MODE/DATA | Multi-function control pin | Configures PFM/PWM mode (low/high) and serves as open-drain serial interface for dynamic voltage adjustment of both outputs. |
| VIN | Main power input | Supplies both converters; must be decoupled with ≥10 μF ceramic capacitor near pin for stability and EMI suppression. |
| FB1 | Converter 1 feedback input | Direct connection to VOUT1 required for closed-loop regulation; internal reference is 600 mV. |
| DEF_1 | Converter 1 output voltage programming input | Analog input for setting VOUT1 via external resistor network; determines default output before EasyScale™ override. |
| SW1, SW2 | Power switch nodes | Connect to respective 2.2 μH inductors; require low-ESR ceramic output capacitors (22 μF typical) and careful layout to minimize switching noise. |
| EN1, EN2 | Independent enable inputs | Active-high control for each converter; allows staggered startup, rail sequencing, and independent power gating in multi-domain SoC systems. |
| GND | Power and signal ground | Must be connected to PCB ground plane; PowerPAD™ underneath die must be soldered to large copper area for thermal and electrical performance. |
Key Features
| Feature | Design Value |
|---|---|
| 180° out-of-phase switching | Reduces input ripple current amplitude by ~30%, allowing smaller input bulk capacitance and lower EMI filter component count. |
| Dynamic voltage positioning (DVP) | Maintains VOUT 1% above nominal in PFM mode to minimize undershoot during sudden load steps-critical for burst-mode DSP operation. |
| 100% duty cycle low-dropout mode | Enables regulation down to VIN – (IOUT × RDS(ON)_PMOS), extending usable battery voltage range and maximizing runtime in Li-Ion applications. |
| EasyScale™ one-pin serial interface | Allows real-time adjustment of both output voltages without additional GPIOs or I²C lines-ideal for adaptive DVFS in OMAP™ and ARM-based platforms. |
| Integrated soft-start | Controls VOUT ramp-up time to 750 μs (95% of final value), preventing inrush current damage to input capacitors and upstream power sources. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62400DRCT | Same 10-pin VSON package and 2.25-MHz operation but limited to 600 mA per channel; no EasyScale™ interface; fixed 1.2 V/1.8 V outputs only. | Suitable for cost-sensitive, fixed-voltage applications where dynamic scaling is unnecessary and load current stays below 600 mA. | Select TPS62400DRCT only if dual 600-mA capability suffices and voltage flexibility is not required-reduces software complexity and eliminates external resistor networks. |
| TPS62590RRLT | Single 1.5-A buck with 2.25-MHz switching and EasyScale™, but no second output; uses 6-pin WSON package; higher peak current but no phase interleaving. | Applicable where only one high-current rail is needed and space constraints favor smaller footprint over dual-rail integration. | Choose TPS62590RRLT when system architecture separates core and I/O power domains or when second rail is supplied by linear regulator-avoids underutilized second channel. |
Compared with TPS62410DRCTG4, TPS62400DRCT trades output flexibility and current headroom for lower cost and simpler design, while TPS62590RRLT offers higher single-rail current density at the expense of dual-rail integration and input ripple reduction benefits.

FAQ
What is the maximum output current per channel for the TPS62410DRCTG4?
The TPS62410DRCTG4 delivers up to 800 mA per channel continuously under recommended operating conditions (TA ≤ 85°C, proper PCB thermal design). This rating assumes adequate copper pour on the PowerPAD™ and ambient airflow; derating applies above 85°C ambient per the 21 mW/°C thermal coefficient specified in the datasheet.
Does the TPS62410DRCTG4 support independent enable control for each output?
Yes, the TPS62410DRCTG4 provides dedicated EN1 and EN2 pins for independent startup, shutdown, and sequencing of each buck converter. Pulling EN1 high activates Converter 1; pulling EN2 high activates Converter 2. Both can operate simultaneously, independently, or in staggered sequence-enabling precise power domain control in multi-rail SoC systems.
Can the TPS62410DRCTG4 operate with a 2.5 V input voltage?
Yes, the TPS62410DRCTG4 supports an input voltage range of 2.5 V to 6 V. At 2.5 V input, it maintains regulation down to VOUT = 0.6 V with appropriate external components, making it suitable for deeply discharged Li-Ion cells and low-voltage industrial rails. Undervoltage lockout triggers at ~1.5 V, ensuring safe operation.
What is the purpose of the MODE/DATA pin on the TPS62410DRCTG4?
The MODE/DATA pin on the TPS62410DRCTG4 serves two functions: (1) selecting operating mode-low enables automatic PFM/PWM transition, high forces fixed-frequency PWM; and (2) acting as an open-drain serial interface for dynamic voltage adjustment of both outputs via TI's EasyScale™ protocol. It requires an external pull-up resistor for interface operation.
How does the TPS62410DRCTG4 achieve high efficiency at light loads?
The TPS62410DRCTG4 achieves high light-load efficiency through automatic entry into power-save mode (PFM), reducing switching frequency and quiescent current to 32 μA for both converters. Combined with dynamic voltage positioning-holding VOUT 1% above nominal-it minimizes energy waste while preserving transient response, unlike fixed-frequency converters that suffer efficiency collapse below 10% load.
