Product details
Overview
TPS61054DRCT from Texas Instruments is a high-power white LED driver IC implementing a 2-MHz synchronous boost converter with integrated low-side current sink, delivering up to 700 mA flash current and 75 mA torch current in a 10-pin VSON (3.0 mm × 3.0 mm) package. It operates in four logic-controlled modes - shutdown, torch-only, torch+flash, and 5.0-V voltage regulation - and features 250-mV LED sense voltage for high efficiency in mobile camera flash applications.
For engineers reviewing the TPS61054DRCT datasheet, TPS61054DRCT pinout, TPS61054DRCT application, or TPS61054DRCT equivalent, key selection considerations include its 700 mA flash capability, zero-latency FLASH_SYNC and Tx-TOFF control inputs, integrated 820-ms safety timer, 0.3 μA shutdown current, and compatibility with 2.2-μH inductors and 10-μF input capacitors in space-constrained smartphone designs.
Technical Context
The TPS61054DRCT uses constant-frequency current-mode PWM control with internal NMOS switch and synchronous NMOS rectifier, operating exclusively in continuous conduction mode to minimize EMI and eliminate switch-node ringing. Its dual-regulation architecture supports both precise LED current sinking (250 mV sense threshold) and regulated 5.0-V output voltage generation.
Logic-driven mode selection (MODE0/MODE1) enables deterministic state transitions between shutdown, torch, flash, and voltage-regulator operation. Flash synchronization is implemented via level-sensitive FLASH_SYNC with built-in 820-ms safety timer, while Tx-TOFF provides zero-latency flash blanking without affecting timer duration - critical for RF coexistence in cellular handsets.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Flash Current | 700 mA - maximum sustained LED drive current in flash mode, enabling bright camera illumination |
| Torch Current | 75 mA - steady-state LED current for video/torch mode, optimized for battery life and thermal management |
| Switching Frequency | 2.0 MHz (±10%) - enables use of compact 2.2-μH inductors and reduces input/output ripple filtering area |
| LED Sense Voltage | 250 mV - low feedback voltage minimizes power loss in current-sink path, boosting overall LED power efficiency |
| Shutdown Current | 0.3 μA typical - ultra-low quiescent draw preserves battery during idle periods in portable devices |
| Output Regulation | 5.0 V ±3% - stable voltage mode output for powering audio amplifiers or other system peripherals |
| Safety Timer Duration | 820 ms - hardware-limited flash-on time prevents thermal damage and ensures compliance with IEC 62471 |
Pinout & Package
TPS61054DRCT is housed in a thermally enhanced 10-pin VSON package (3.0 mm × 3.0 mm, 0.5-mm pitch) with exposed thermal pad connected internally to PGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AVIN | Input Power Supply | Main input voltage connection (2.5–6 V); must be decoupled with ≥10-μF capacitor directly at pin |
| VOUT | Boost Output | Regulated output node; supplies LED anode or external 5-V load; connects to output capacitor |
| SW | Power Switch Node | Drain of internal NMOS switch; connects to inductor switch node; high-impedance during shutdown |
| LED | Current-Sense Feedback | Low-side current-sense input; regulates LED current by maintaining 250 mV across internal sense resistor |
| FLASH_SYNC | Flash Trigger Input | Level-sensitive strobe: HIGH = flash mode (700 mA), LOW = torch mode (75 mA); starts 820-ms safety timer |
| MODE0 / MODE1 | Mode Selection Inputs | Binary-coded control: (0,0)=shutdown, (1,0)=torch only, (0,1)=torch+flash, (1,1)=5-V voltage regulation |
| Tx-TOFF | RF Blanking Input | Zero-latency flash-to-torch transition during TX bursts; does not reset or affect safety timer duration |
| PGND / AGND | Ground Returns | PGND = power ground (connects to thermal pad); AGND = analog reference ground; separate routing required |
Key Features
| Feature | Design Value |
|---|---|
| Four Logic-Controlled Operating Modes | Enables single-chip support for torch, flash, shutdown, and 5-V supply functions - reducing BOM count and PCB area |
| Integrated 820-ms Safety Timer | Hardware-enforced flash duration prevents LED overheating and meets photobiological safety standards without firmware |
| Zero-Latency Tx-TOFF Blanking | Sub-microsecond flash dimming during RF transmission eliminates battery current spikes and avoids interference with cellular TX |
| 250-mV LED Sense Voltage | Minimizes power dissipation in current-sink path, achieving up to 96% LED power efficiency at 700 mA |
| Open/Short LED Protection | Automatically limits output current during short-circuit failure and clamps VOUT to 6.0 V during open-circuit conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar white LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61055DRCT | Lower flash current limit (500 mA vs. 700 mA); identical torch current (75 mA), safety timer (820 ms), and pinout | Targeted at lower-power flash systems where thermal budget or LED rating restricts peak current | Select when 500 mA flash suffices and higher efficiency at mid-load is prioritized over peak brightness |
| RT8532GQW | Fixed 600 mA flash current; no voltage-regulation mode; lacks Tx-TOFF and FLASH_SYNC inputs; 12-pin QFN | Designed solely for flash/torch operation - no secondary 5-V supply capability | Choose when system requires only LED driving and simpler control interface without RF-blanking or auxiliary power needs |
Compared with TPS61055DRCT, the TPS61054DRCT delivers 40% higher flash current for superior low-light imaging, while RT8532GQW offers reduced feature set and footprint but omits critical camera-synchronization functions and dual-mode operation.

FAQ
What are the key differences between TPS61054DRCT and TPS61055DRCT?
The TPS61054DRCT supports 700 mA flash current and 1500 mA current limit (ILIM = 01), whereas the TPS61055DRCT is rated for 500 mA flash current and 1000 mA current limit (ILIM = 00). Both share identical torch current (75 mA), safety timer (820 ms), pinout, and functional modes. The TPS61054DRCT is selected when higher flash brightness is required without changing layout or firmware.
How does the FLASH_SYNC pin function in TPS61054DRCT?
In TPS61054DRCT, the FLASH_SYNC pin is a level-sensitive input: applying HIGH (≥1.2 V) switches the device to flash mode (700 mA), while LOW (≤0.4 V) selects torch mode (75 mA). A rising edge initiates the 820-ms hardware safety timer, which expires independently of the pin state - ensuring safe thermal operation regardless of host timing accuracy.
Does TPS61054DRCT support voltage regulation mode, and what is its accuracy?
Yes, TPS61054DRCT supports voltage-regulation mode when MODE0 = MODE1 = 1, delivering a regulated 5.0 V output. Its DC output voltage accuracy is ±3% over input voltage (2.5–6 V) and load (0–1000 mA) ranges, with typical efficiency exceeding 85% at 500 mA - making it suitable for powering audio amplifiers or other 5-V peripherals.
What protection features are integrated into TPS61054DRCT?
TPS61054DRCT integrates open/short LED protection, thermal shutdown (160°C typical), undervoltage lockout (2.4 V threshold), overvoltage protection (6.0 V clamp), and LED disconnect during shutdown. During open-circuit failure, VOUT is limited to 6.0 V; during short-circuit, current is capped at 1500 mA - ensuring robust operation without external supervision.
Can TPS61054DRCT drive multiple LEDs in series?
No, TPS61054DRCT is designed exclusively for single-white-LED operation. Its 250-mV LED sense architecture and fixed current-sink topology assume one LED cathode connected to the LED pin. Driving multiple series LEDs would exceed the 5.5-V maximum VOUT rating in boost mode and invalidate the 250-mV regulation point - requiring a different driver architecture.
