Краткое описание:
Dual-Output Boost WLED Driver with Single Inductor and PWM Dimming
Дополнительная информация
The TPS61151 is a dual-output boost converter designed to drive up to two strings of 6 white LEDs each using only a single inductor. It features a 1.2-MHz fixed switching frequency and integrated 0.7-A switch, providing an efficient solution for small-sized LCD backlighting. The device includes a built-in power diode, synchronous rectification, and supports PWM dimming to control LED brightness.
