Краткое описание:
2-MHz Synchronous Boost Converter with LED Driver and 5-V/700-mA Support
Дополнительная информация
The TPS61054 is a high-frequency synchronous boost converter with a constant current sink designed to drive single white LEDs. It operates as both a regulated current source for Flash/Torch modes and a standard 5.0-V voltage-boost regulator. The device utilizes a 2-MHz switching frequency allowing for a total solution circuit area of less than 25 mm², featuring inductive fixed-frequency PWM control and integrated safety timers.
