Product details
Overview
TPS62410QDRCRQ1 from Texas Instruments is an AEC-Q100 qualified dual synchronous step-down DC-DC converter for automotive battery-powered systems. It delivers two independent 800mA output rails (VOUT1/VOUT2) from a 2.5V–6V input, operates at 2.25MHz fixed frequency, supports Power Save Mode (PFM) and forced PWM operation via MODE/DATA pin, and enables dynamic voltage scaling in smart infotainment and ADAS domain controllers.
For engineers reviewing the TPS62410QDRCRQ1 datasheet, TPS62410QDRCRQ1 pinout, TPS62410QDRCRQ1 application, or TPS62410QDRCRQ1 equivalent, key selection considerations include its 10-pin 3×3mm QFN package, dual-channel 800mA capability with 180° phase shift, ±1% output accuracy in PWM mode, 32µA typical quiescent current for both converters, and EasyScale™ one-wire interface for real-time output voltage adjustment.
Technical Context
The TPS62410QDRCRQ1 integrates two independent synchronous buck regulators sharing a 2.25MHz oscillator with 180° phase offset to reduce input RMS current ripple. Each channel features internal compensation, voltage-mode control with input feed-forward, and dual MOSFET current limiting (P-ch RDS(ON) typ. 280mΩ, N-ch RDS(ON) typ. 200mΩ).
Power Save Mode activates automatically below ~10–30mA load per channel (VIN-dependent), entering PFM with 1.01×VOUT voltage positioning and skip-comparator-based regulation; forced PWM mode is selected by pulling MODE/DATA high, ensuring constant frequency operation across full load range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 2.5V to 6V - supports single-cell Li-ion (2.7–4.2V), 3.3V/5V rails, and automotive cold-crank down to 2.5V. |
| Output Current | 2 × 800mA - each channel independently delivers up to 800mA continuous output with thermal shutdown at 150°C. |
| Switching Frequency | 2.25MHz fixed - enables use of small 2.2µH inductors and 22µF ceramic output capacitors for compact layout. |
| Efficiency | Up to 95% - achieved at mid-load (e.g., 200mA) with VIN=3.6V, VOUT1=1.5V, VOUT2=1.8V. |
| Quiescent Current | 32µA (both converters, PFM mode) - maintains ultra-low standby power in always-on automotive modules. |
| Output Accuracy | ±1% in PWM mode - ensures stable core voltage for DSPs and microcontrollers without external trimming. |
| Interface | EasyScale™ one-wire serial - allows dynamic VOUT adjustment during operation using MODE/DATA pin with acknowledge support. |
Pinout & Package
TPS62410QDRCRQ1 is housed in a thermally enhanced 10-pin QFN package (3mm × 3mm, 0.5mm pitch) with exposed PowerPAD™ for improved thermal dissipation. The package is RoHS-compliant and rated for –40°C to +125°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 ADJ2 | Converter 2 output voltage adjust input | Connects to external resistor divider for adjustable VOUT2; must tie directly to VOUT2 when using EasyScale™ interface. |
| 2 MODE/DATA | Mode selection & serial interface I/O | Pull low for automatic PFM/PWM transition; pull high for forced PWM; serves as bidirectional EasyScale™ data line with open-drain acknowledge. |
| 3 VIN | Main power input | Accepts 2.5V–6V supply; requires 10µF ceramic input capacitor close to pin for stability and EMI reduction. |
| 4 FB1 | Converter 1 feedback sense | Direct connection to VOUT1; provides precise voltage regulation path for internal error amplifier. |
| 5 DEF_1 | Converter 1 default output setting | Analog input for external resistor network to set VOUT1 between 0.6V and VIN. |
| 6 SW1 | Converter 1 high-side switch node | Connects to 2.2µH inductor; requires low-ESR ceramic output capacitor and careful PCB layout to minimize switching noise. |
| 7 EN1 | Converter 1 enable control | Active-high digital input; independent enable allows staggered startup or power sequencing of dual rails. |
| 8 GND | Power and signal ground | Must be connected to exposed PowerPAD™; forms low-impedance return path for both converters and reduces thermal resistance. |
| 9 EN2 | Converter 2 enable control | Active-high digital input; enables/disables second channel independently of EN1 for flexible power management. |
| 10 SW2 | Converter 2 high-side switch node | 180° out-of-phase with SW1; reduces input capacitor RMS current and improves EMI performance. |
Key Features
| Feature | Design Value |
|---|---|
| 180° phase-shifted dual outputs | Reduces input capacitor RMS current by ~30%, enabling smaller 10µF input capacitance and lower EMI filtering cost. |
| Dynamic Voltage Positioning (DVP) | Maintains VOUT at 1.01× nominal in PFM mode, minimizing undershoot during light-to-heavy load transients in processor cores. |
| 100% duty cycle operation | Extends battery runtime by sustaining regulation down to VIN = VOUT + IOUT×RDS(ON) + IOUT×RL, critical for deep discharge in automotive telematics. |
| Integrated soft-start | Controls VOUT ramp-up time (~750µs to 95%) to limit inrush current and prevent system brownout during power-on reset. |
| Thermal shutdown with hysteresis | Shuts down at 150°C junction temperature and re-enables at 130°C, preventing thermal runaway in sealed enclosures. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output buck regulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62420QDRCRQ1 | Same pinout and package; fixed 1.8V/2.5V outputs (no ADJ2/DEF_1 pins); no EasyScale™ interface. | Suitable only for designs requiring factory-set voltages without runtime adjustment. | Select when output voltages are static and board space is constrained-eliminates external resistor networks but forfeits flexibility. |
| LMQ66430QRNXTQ1 | Single-channel 3A buck; 2.5V–36V input; 2.1MHz switching; no integrated EasyScale™ or phase-shift capability. | Requires two separate ICs to replicate dual-rail functionality; higher VIN range supports direct 12V battery input. | Choose for high-input-voltage applications (>6V) or where >800mA per rail is needed-adds complexity but extends operating range. |
Compared with TPS62410QDRCRQ1, TPS62420QDRCRQ1 offers simplified BOM for fixed-voltage use cases but lacks dynamic adjustment, while LMQ66430QRNXTQ1 supports wider input range and higher current but increases component count and eliminates phase-shifting benefits for EMI reduction.

FAQ
What is the maximum output current per channel for the TPS62410QDRCRQ1?
The TPS62410QDRCRQ1 delivers up to 800mA continuous output current per channel under recommended operating conditions (TJ ≤ 125°C, 2.5V ≤ VIN ≤ 6V). Peak current limit is 1.0–1.38A depending on input voltage and temperature, with thermal shutdown activating at 150°C to protect the device.
How does the MODE/DATA pin control operation mode in the TPS62410QDRCRQ1?
The MODE/DATA pin serves dual functions: when pulled low (≤0.4V), it enables automatic Power Save Mode (PFM at light loads, PWM at heavy loads); when pulled high (≥1.2V), it forces fixed-frequency PWM operation across the full load range. It also acts as the bidirectional data line for the EasyScale™ interface when either EN1 or EN2 is asserted.
Can the TPS62410QDRCRQ1 operate with a 2.5V input supply?
Yes, the TPS62410QDRCRQ1 supports a minimum input voltage of 2.5V, making it suitable for automotive cold-crank conditions and single-cell Li-ion battery operation. At 2.5V input, it maintains regulation down to VOUT = 0.6V with 100% duty cycle enabled, provided load current and component losses remain within specification.
What is the purpose of Dynamic Voltage Positioning in the TPS62410QDRCRQ1?
Dynamic Voltage Positioning (DVP) in the TPS62410QDRCRQ1 regulates the output voltage to 1.01× nominal in Power Save Mode. This intentional overvoltage provides margin to absorb load-step undershoot, reducing voltage dip by up to 40mV during sudden current increases-critical for stable operation of voltage-sensitive processors in automotive ECUs.
Is the TPS62410QDRCRQ1 pin-compatible with other devices in the TPS624xx-Q1 family?
The TPS62410QDRCRQ1 shares the same 10-pin QFN (DRC) package and pinout with TPS62420QDRCRQ1 and TPS62400QDRCRQ1, enabling drop-in replacement for certain variants. However, functional differences exist: TPS62420 has fixed outputs and no EasyScale™, while TPS62400 supports only single-output configuration-always verify peripheral circuit compatibility before substitution.
