Product details
Overview
TPS62407QDRCRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive dual synchronous step-down DC-DC converter delivering fixed 1.225 V @ 400 mA (Channel 1) and 1.85 V @ 600 mA (Channel 2) from a 2.5–6 V input, operating at 2.25 MHz with 180° out-of-phase switching for reduced input ripple-used in ADAS camera modules to power CMOS image sensors and SerDes ICs.
For engineers reviewing the TPS62407QDRCRQ1 datasheet, TPS62407QDRCRQ1 pinout, TPS62407QDRCRQ1 application, or TPS62407QDRCRQ1 equivalent, key selection criteria include its dual-channel automotive-grade efficiency (up to 95%), ±1% PWM-mode output accuracy, 32-μA quiescent current (both channels active), EasyScale™ one-pin dynamic voltage scaling capability, and thermal shutdown protection at 150°C.
Technical Context
The TPS62407QDRCRQ1 integrates two independent voltage-mode PWM controllers with input-voltage feed-forward, enabling fast line/load regulation using small ceramic capacitors. Each channel features integrated P- and N-MOSFETs with rDS(on) of 280 mΩ (P) and 200 mΩ (N) at 3.6 V, plus dual current limiting and automatic transition between PWM and PFM modes via MODE/DATA pin control.
It supports 180° out-of-phase operation to minimize input RMS current and peak surge draw, while its EasyScale™ interface-multiplexed on the MODE/DATA pin-enables runtime adjustment of both output voltages without additional pins. The DEF_1 pin selects between two internal voltage registers, though for TPS62407QDRCRQ1 both states yield the same 1.225 V default on Channel 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 2.5 V to 6 V - supports direct connection to automotive 3.3-V or 5-V rails without pre-regulation |
| Switching Frequency | 2.25 MHz fixed - enables use of compact 2.2-μH inductors and low-ESR ceramic capacitors |
| Output Voltages | Channel 1: 1.225 V (fixed); Channel 2: 1.85 V (fixed) - optimized for CMOS imager core and I/O supply rails |
| Output Current | 400 mA (CH1), 600 mA (CH2) - sufficient for dual-rail power in ADAS camera sensor + serializer subsystems |
| Quiescent Current | 32 μA typical (both converters active, no load, PFM mode) - extends battery life in always-on vehicle systems |
| Output Accuracy | ±1% in PWM mode - ensures stable logic-level compliance for sensitive imaging and signal-chain ICs |
| Thermal Shutdown | 150°C with 20°C hysteresis - protects against sustained overload or poor PCB thermal design |
Pinout & Package
VSON-10 (DRC) package, 3.00 mm × 3.00 mm body size with exposed thermal pad (connected to GND).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| ADJ2 (Pin 1) | Feedback sense for Channel 2 | Must connect directly to VOUT2; required for EasyScale™ operation on CH2 |
| DEF_1 (Pin 5) | Digital voltage select for Channel 1 | Configures internal register; for TPS62407QDRCRQ1, both high/low yield 1.225 V |
| EN1 / EN2 (Pins 7, 9) | Independent enable inputs | Active-high; allows staggered startup and per-channel power gating in multi-rail systems |
| FB1 (Pin 4) | Feedback sense for Channel 1 | Connects directly to VOUT1; sets regulation point for fixed 1.225 V output |
| MODE/DATA (Pin 2) | Mode control & serial interface | Pull low for auto PFM/PWM transition; pull high for forced PWM; carries EasyScale™ commands |
| SW1 / SW2 (Pins 6, 10) | Power switch nodes | Connect to respective 2.2-μH inductors; require low-inductance layout to minimize EMI |
| VIN (Pin 3) | Main input supply | Accepts 2.5–6 V; requires local 10-μF ceramic capacitor placed adjacent to pin and GND |
| GND (Pin 8) + Thermal Pad | Power and signal reference | Single ground plane connection; thermal pad must be soldered to PCB copper for thermal performance |
Key Features
| Feature | Design Value |
|---|---|
| 180° out-of-phase operation | Reduces input capacitor RMS current by ~30%, enabling smaller input bulk capacitance |
| EasyScale™ one-pin interface | Enables dynamic voltage scaling of both outputs without extra GPIOs or I²C lines |
| Power-save mode (PFM) | Maintains >85% efficiency down to 100 μA load per channel, critical for standby camera systems |
| 100% duty cycle capability | Supports ultra-low dropout operation when VIN approaches VOUT, e.g., 1.85 V output from 2.0 V rail |
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C junction operation, meeting stringent automotive reliability requirements |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-output automotive buck converter applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS62422QDRCRQ1 | Higher CH1 current (1000 mA vs 400 mA); different fixed outputs (1.8 V / 1.2 V) | Better suited for processors requiring higher core current; less optimal for sensor+SerDes split-rail loads | Select when CH1 load exceeds 400 mA or 1.8 V/1.2 V rail pairing matches system architecture |
| TPS62423QDRCRQ1 | Matched 800 mA per channel; fixed 1.5 V / 1.8 V outputs; no DEF_1 pin flexibility | Ideal for symmetric dual-core SoCs or memory interfaces needing matched current capability | Choose for balanced dual-rail loads where 1.5 V/1.8 V alignment improves power tree efficiency |
Compared with TPS62407QDRCRQ1, TPS62422QDRCRQ1 offers greater CH1 headroom but mismatched rail voltages for camera modules, while TPS62423QDRCRQ1 provides symmetrical current capacity at the cost of fixed 1.5 V/1.8 V outputs-neither is pin-compatible, requiring PCB redesign for substitution.

FAQ
What is the default output voltage configuration of the TPS62407QDRCRQ1?
The TPS62407QDRCRQ1 has fixed output voltages: Channel 1 delivers 1.225 V at up to 400 mA, and Channel 2 delivers 1.85 V at up to 600 mA. Unlike other variants in the family, the DEF_1 pin does not change the output voltage-it remains 1.225 V regardless of DEF_1 logic level. This simplifies design for camera sensor power where consistent core voltage is required.
How does the TPS62407QDRCRQ1 manage efficiency across varying load conditions?
The TPS62407QDRCRQ1 automatically transitions between PWM and PFM modes based on load: it operates in fixed-frequency 2.25-MHz PWM mode above ~120 mA (calculated via VIN/32 Ω), then enters PFM for light loads to maintain >85% efficiency down to microamp levels. Quiescent current is just 32 μA with both channels active and no load, making it ideal for always-on ADAS subsystems.
Can the TPS62407QDRCRQ1 support dynamic voltage scaling, and how is it implemented?
Yes-the TPS62407QDRCRQ1 supports dynamic voltage scaling via its EasyScale™ one-pin serial interface on the MODE/DATA pin. Using a simple master-driven protocol (address 0x4E), a microcontroller can adjust both output voltages in real time without additional communication lines. For TPS62407QDRCRQ1, this enables runtime optimization of sensor core and I/O voltages during different imaging modes (e.g., low-power standby vs full-resolution capture).
What thermal protection mechanisms are built into the TPS62407QDRCRQ1?
The TPS62407QDRCRQ1 includes thermal shutdown that activates at 150°C junction temperature, turning off both P- and N-MOSFETs until temperature falls below 130°C (20°C hysteresis). Combined with its VSON-10 package's low RθJB of 18.1°C/W and exposed thermal pad, this ensures reliable operation in sealed camera housings-even under sustained 600 mA load at 125°C ambient-without external thermal monitoring circuitry.
Is the TPS62407QDRCRQ1 pin-compatible with other devices in the TPS624xx-Q1 family?
No-the TPS62407QDRCRQ1 is not pin-compatible with other TPS624xx-Q1 variants such as TPS62422QDRCRQ1 or TPS62423QDRCRQ1. Although all share the VSON-10 (DRC) package, differences in internal feedback networks, current limits, and voltage defaults mean substituting parts requires validation of loop stability, thermal performance, and system-level voltage margining-not just PCB footprint reuse.
