Product details
Overview
TPS62410 from Texas Instruments is a synchronous dual step-down DC–DC converter delivering two independent 800-mA output rails from a 2.5 V to 6 V input, operating at 2.25 MHz with ±1% PWM-mode output voltage accuracy and up to 95% peak efficiency. It supports dynamic voltage scaling via EasyScale™ one-pin serial interface and enables 180° out-of-phase operation to reduce input ripple in portable power systems such as OMAP™ processor cores and smartphone application processors.
For engineers reviewing the TPS62410 datasheet, TPS62410 pinout, TPS62410 application, or TPS62410 equivalent, key selection considerations include its dual-channel 800-mA capability, 2.25-MHz fixed-frequency PWM mode, power-save mode quiescent current of 32 μA (both converters), 10-pin VSON (3 mm × 3 mm) package with exposed thermal pad, and support for adjustable outputs from 0.6 V to VIN using external resistor networks on DEF_1 and ADJ2 pins.
Technical Context
The TPS62410 integrates two independent synchronous buck regulators sharing a single 2.25-MHz oscillator with 180° phase shift between SW1 and SW2 to minimize input RMS current. Each channel features separate enable (EN1/EN2), feedback (FB1), and voltage-setting inputs (DEF_1 for Channel 1, ADJ2 for Channel 2), enabling independent startup, regulation, and dynamic reconfiguration.
Its control architecture combines voltage-mode PWM with input-voltage feed-forward for fast line/load transient response, plus automatic transition between fixed-frequency PWM and pulse-frequency modulation (PFM) power-save mode based on load current thresholds. Dynamic voltage positioning adjusts regulated output to +1% nominal during light loads to suppress undershoot during sudden load steps.
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-cell NiMH/NiCd (3.6–4.5 V), or standard 3.3 V/5 V rails without external LDO pre-regulation. |
| Output Current | 2 × 800 mA - each channel delivers full rated current simultaneously with thermal derating per RθJA = 45.9°C/W. |
| Switching Frequency | 2.25 MHz (±12.5%) - enables use of small 2.2-μH inductors and 22-μF ceramic output capacitors for compact PCB layout. |
| Output Voltage Accuracy | ±1% in PWM mode - ensures stable core voltage for DSPs and application processors under varying load and temperature (–40°C to 85°C). |
| Quiescent Current | 32 μA (both converters, PFM mode) - extends battery runtime in standby/sleep states of portable devices. |
| Shutdown Current | 1.2 μA - minimizes battery drain when both EN1 and EN2 are low, critical for always-on subsystems. |
| Efficiency Peak | Up to 95% - achieved at mid-load (e.g., 300 mA @ 3.3 VOUT, 3.6 VIN), reducing thermal stress and enabling fanless designs. |
Pinout & Package
The TPS62410 is housed in a thermally enhanced 10-pin VSON package (3.00 mm × 3.00 mm) with an exposed PowerPAD™ on the bottom side that must be soldered to a PCB thermal plane for optimal junction-to-board thermal resistance (RθJB = 20.4°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ADJ2 (Pin 1) | Converter 2 output voltage programming input | Analog input for external resistor divider; when used with EasyScale™, must be tied directly to VOUT2 - no external resistors allowed. |
| MODE/DATA (Pin 2) | Multi-function control terminal | Logic-low enables auto PWM/PFM mode; logic-high forces fixed-frequency PWM; also serves as open-drain serial data/acknowledge line for EasyScale™. |
| VIN (Pin 3) | Main power input | Supplies both converters; accepts 2.5–6 V with undervoltage lockout (UVLO) threshold of 1.5 V (rising) to prevent brownout operation. |
| FB1 (Pin 4) | Converter 1 feedback sense node | Direct connection to VOUT1 required; internal feed-forward capacitor improves transient response; not used in fixed-output variants. |
| DEF_1 (Pin 5) | Converter 1 output voltage programming input | Analog input for external resistor network to set VOUT1 from 0.6 V to VIN; determines default voltage before EasyScale™ override. |
| SW1 (Pin 6) | Converter 1 high-side switch node | Connects to inductor L1; carries pulsed current up to 1.38 A peak; requires low-ESR ceramic input capacitor near VIN. |
| EN1 (Pin 7) | Converter 1 enable input | Active-high digital control; independent startup/shutdown of Channel 1; must not float - tie to GND or VIN via pull-up/down. |
| GND (Pin 8) | Power and signal reference | Common ground for both converters and control circuitry; PowerPAD™ must be connected to this net for thermal and EMI performance. |
| EN2 (Pin 9) | Converter 2 enable input | Active-high digital control; independent from EN1 - allows staggered sequencing or asymmetric power management. |
| SW2 (Pin 10) | Converter 2 high-side switch node | Connects to inductor L2; operates 180° out-of-phase with SW1 to halve input ripple current magnitude at 2.25 MHz. |
Key Features
| Feature | Design Value |
|---|---|
| 180° out-of-phase switching | Reduces input capacitor RMS current by ~30% versus in-phase operation, allowing smaller 10-μF CIN instead of 22-μF. |
| Dynamic voltage positioning | Maintains VOUT at +1% nominal in PFM mode to limit undershoot to ≤2% during 0→800 mA load steps without external compensation. |
| 100% duty cycle low-dropout mode | Enables regulation down to VIN − VOUT ≈ 300 mV (at 800 mA), extending usable battery voltage range in Li-ion systems. |
| EasyScale™ one-pin serial interface | Allows real-time adjustment of both VOUT1 and VOUT2 via MODE/DATA pin without additional GPIOs or I²C lines. |
| Thermal shutdown with hysteresis | Shuts down at TJ ≥ 150°C and resumes at TJ ≤ 130°C, preventing thermal runaway during sustained overload or poor heatsinking. |

FAQ
What is the maximum output current per channel for the TPS62410?
The TPS62410 delivers up to 800 mA per channel continuously under recommended operating conditions (TA ≤ 85°C, proper PCB thermal design). Peak current capability reaches 1.38 A per channel, as defined by the forward current limit (ILIMF) specification. Actual sustained current depends on ambient temperature, input voltage, and thermal management - with full 800 mA achievable on both channels simultaneously when using the exposed PowerPAD™ and adequate copper area.
Does the TPS62410 support dynamic voltage scaling during operation?
Yes, the TPS62410 supports real-time dynamic voltage scaling via its EasyScale™ one-pin serial interface on the MODE/DATA pin. This allows in-system adjustment of both VOUT1 and VOUT2 without requiring additional communication buses or firmware overhead. The interface uses open-drain signaling with acknowledge pulses, enabling voltage changes in under 500 μs - critical for DVFS in application processors and low-power DSPs.
What package type and thermal characteristics does the TPS62410 use?
The TPS62410 is packaged in a 10-pin VSON (DRC) case measuring 3.00 mm × 3.00 mm with an exposed thermal pad (PowerPAD™). Its thermal metrics include RθJA = 45.9°C/W (junction-to-ambient, JEDEC standard), RθJB = 20.4°C/W (junction-to-board), and RθJC(bot) = 2.8°C/W (junction-to-case bottom). Proper soldering of the PowerPAD™ to a multi-layer PCB thermal plane is mandatory to achieve rated current and reliability.
How does the TPS62410 manage efficiency across light and heavy load conditions?
The TPS62410 automatically transitions between fixed-frequency PWM mode (for medium/heavy loads) and pulse-frequency modulation (PFM) power-save mode (for light loads) using the MODE/DATA pin configuration. In PFM mode, quiescent current drops to 32 μA for both converters, sustaining >85% efficiency down to 1 mA load. At full 800 mA, peak efficiency reaches 95% - enabled by synchronous rectification, low RDS(on) MOSFETs (280 mΩ P-ch / 200 mΩ N-ch), and 2.25-MHz operation minimizing passive size.
Can the TPS62410 operate with a single-cell Li-ion battery input?
Yes, the TPS62410 is explicitly designed for single-cell Li-ion battery operation, supporting an input range of 2.5 V to 6 V - fully covering the Li-ion discharge curve (4.2 V down to 2.7 V nominal, with UVLO protecting down to 1.5 V). Its 100% duty-cycle mode maintains regulation even at low VIN, and dynamic voltage positioning compensates for battery voltage sag during high-current bursts, ensuring stable core voltage for processors throughout battery life.
