The Texas Instruments TPS61054YZGR is a high-frequency synchronous-boost topology LED driver. It is designed to drive single white LEDs with a constant current sink, capable of up to 700mA for flash applications. The device utilizes a fixed-frequency PWM control scheme, enabling the use of small external components like 2.2-µH inductors.
This LED driver IC operates with a low 250-mV LED feedback voltage to optimize efficiency, reaching up to 96%. It can function not only as a regulated current source but also as a standard voltage-boost regulator, providing flexibility for other system components. The output voltage can be programmed via logic signals, and a FLASH_SYNC trigger pin simplifies synchronization with camera modules.
The TPS61054YZGR is available in a compact 12-DSBGA package, suitable for surface mount applications. It operates within a temperature range of -40°C to 85°C (TA) and features integrated safety protections such as open/shorted LED protection and over-temperature protection. In shutdown mode, the device draws a typical input current of 0.3 µA.
Key applications include camera white LED torch or flash for mobile phones, smartphones, and PDAs, as well as general lighting applications and powering audio amplifiers.
