Dual Output Boost Converter for OLED and WLED
Дополнительная информация
The TPS61141 is a dual output boost regulator designed to provide both a regulated voltage and a regulated current from a single inductor. It is specifically optimized for driving an OLED sub-display and a WLED backlight for LCD main displays. It features a 1.2-MHz PWM control for WLED driving and PFM control for the OLED supply to maintain high efficiency. The device includes a 0.7-A integrated switch, power diode, and input-to-output isolation.
