Product details
Overview
TPS61054YZGT from Texas Instruments is a high-power white LED driver IC featuring a 2-MHz synchronous boost converter with integrated current-sink regulation, supporting torch (75 mA) and flash (700 mA) modes, 250-mV LED sense voltage, and 5.0-V regulated output mode - used in smartphone camera flash subsystems requiring fast FLASH_SYNC-triggered current transitions.
For engineers reviewing the TPS61054YZGT datasheet, TPS61054YZGT pinout, TPS61054YZGT application, or TPS61054YZGT equivalent, key selection criteria include its dual-mode operation (current-regulated LED drive + voltage-boost), zero-latency Tx-TOFF flash blanking, integrated 820-ms safety timer, and DSBGA-12 NanoFree™ packaging for ultra-compact mobile designs.
Technical Context
The TPS61054YZGT implements a constant-frequency, current-mode PWM control architecture with internal NMOS switch and synchronous NMOS rectifier, operating exclusively in continuous-conduction mode to suppress switching noise and eliminate discontinuous-mode ringing. Its 2-MHz oscillator enables use of small 2.2-μH inductors and minimizes input ripple.
It supports four distinct functional modes via MODE0/MODE1 logic inputs: shutdown (0.3 μA IQ), torch-only, torch+flash, and 5.0-V voltage regulation - with FLASH_SYNC enabling immediate transition to flash current and Tx-TOFF forcing instantaneous downshift to torch current without affecting safety timer duration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switching frequency | 2.0 MHz ±10% - enables compact 2.2-μH inductor and low-profile layout |
| LED current accuracy | ±12% at 700 mA flash - ensures consistent brightness across units and temperature |
| LED sense voltage | 250 mV typical - minimizes power loss in current-sense path, boosting efficiency |
| Shutdown current | 0.3 μA typical - preserves battery life during idle periods in portable devices |
| Output overvoltage protection | 6.0 V typical - safeguards downstream circuitry during open-LED fault conditions |
| Thermal shutdown threshold | 160°C typical - protects silicon integrity under sustained high-current or poor thermal dissipation |
| Input voltage range | 2.5 V to 6.0 V - compatible with single-cell Li-ion (3.0–4.2 V) and extended-range batteries |
Pinout & Package
TPS61054YZGT is housed in a 12-pin DSBGA (Die Size Ball Grid Array) package measuring 1.96 mm × 1.46 mm with 0.4-mm ball pitch. The thermal pad is internally connected to PGND and must be soldered to PCB ground for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AVIN | Input power supply | Primary input connection for battery or source; requires local 10-μF bypass capacitor |
| VOUT | Boost output node | Regulated output for LED anode or external 5-V rail; connects to output capacitor |
| LED | Current-sense feedback | Low-side current-sense input; regulates LED current via 250-mV reference |
| SW | Power switch node | Drain of internal NMOS switch; connects to inductor switch node; high-impedance in shutdown |
| PGND | Power ground | High-current return path for switch and rectifier; tied to thermal pad and AGND |
| AGND | Analog ground | Reference for internal error amplifier and bandgap; must be shorted to PGND at single point |
| MODE0 / MODE1 | Mode selection inputs | Digital control pins defining operational state (shutdown/torch/flash/voltage-reg); must not float |
| FLASH_SYNC | Flash strobe trigger | Level-sensitive input: HIGH enables flash current (700 mA), LOW maintains torch (75 mA) |
| Tx-TOFF | RF TX masking input | Zero-latency blanking: HIGH forces immediate shift to torch current to reduce RF interference |
Key Features
| Feature | Design Value |
|---|---|
| Four selectable operating modes | Configurable via MODE0/MODE1: shutdown, torch-only, torch+flash, and 5.0-V voltage regulation |
| Integrated 820-ms safety timer | Starts on FLASH_SYNC rising edge; prevents thermal damage during prolonged flash operation |
| Zero-latency Tx-TOFF blanking | Instantaneous LED current reduction from flash to torch without interrupting safety timer timing |
| 250-mV LED sense voltage | Minimizes conduction loss in current-path, enabling >90% efficiency in linear-down mode |
| Open/short LED protection | Clamps VOUT to 6.0 V during open-circuit fault; limits current to 1500 mA during short-circuit |
| Low-light PWM dimming | 122-Hz, 6.3% duty-cycle modulation activated in torch mode with FLASH_SYNC = HIGH |

Equivalent & Alternatives
The following parts are listed as comparable options for similar white LED driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS61055YZGT | Lower flash current limit (500 mA vs. 700 mA); identical pinout, package, and feature set | Suitable for lower-power flash systems where thermal budget or LED rating restricts peak current | Select TPS61055YZGT when flash intensity requirements are ≤500 mA and thermal margin is constrained |
| LM3644YFQR | 2-MHz boost with I²C interface, programmable current (up to 1500 mA), and thermal foldback | Requires digital control bus; supports dynamic current scaling and fault reporting unavailable in TPS61054YZGT | Choose LM3644YFQR when system-level flexibility, diagnostics, or higher flash current (>700 mA) is required |
Compared with TPS61055YZGT, the TPS61054YZGT delivers 40% higher flash current for brighter imaging; compared with LM3644YFQR, it offers simpler GPIO-based control and lower system-level complexity but lacks programmability and telemetry.

FAQ
What is the maximum flash current supported by the TPS61054YZGT?
The TPS61054YZGT supports a maximum flash current of 700 mA, as specified in the device options table and confirmed in electrical characteristics under ILED = IFLASH test conditions. This value is fixed for the YZG package variant and does not require external programming - it is enabled automatically when FLASH_SYNC is driven HIGH and MODE0/MODE1 are set to torch+flash mode.
Does the TPS61054YZGT require external compensation components?
No, the TPS61054YZGT integrates full internal compensation for its current-mode PWM control loop. The device operates stably with only the required external components: 2.2-μH inductor, 10-μF input capacitor, and output capacitor - no external RC networks or compensation pins are present or needed for standard operation.
How does the TPS61054YZGT handle LED open-circuit faults?
When an LED open-circuit fault occurs, the TPS61054YZGT's feedback loop attempts to regulate current but cannot achieve it, causing VOUT to rise until the internal overvoltage protection activates at approximately 6.0 V. This clamps the output and prevents damage to the IC or other system components while maintaining safe operating conditions.
Can the TPS61054YZGT operate as a standalone voltage regulator?
Yes, the TPS61054YZGT can operate as a regulated 5.0-V boost converter when configured with MODE0 = 1 and MODE1 = 1. In this mode, it regulates VOUT to 5.0 V ±3% across load currents up to 1 A and input voltages from 2.5 V to 6.0 V - making it suitable for powering auxiliary rails like audio amplifiers without requiring additional regulators.
What is the purpose of the Tx-TOFF pin on the TPS61054YZGT?
The Tx-TOFF pin on the TPS61054YZGT provides zero-latency flash blanking: when driven HIGH, it forces immediate reduction of LED current from flash level (700 mA) to torch level (75 mA) to minimize RF interference during cellular transmission. Unlike FLASH_SYNC, Tx-TOFF does not reset or affect the 820-ms safety timer duration.
