Краткое описание:
45-V LED backlight driver with three channels 120-mA output
Дополнительная информация
The TPS92380 is a highly-integrated, high output power LED driver with an integrated DC-DC converter supporting both boost and SEPIC mode operation. It features three high-precision current sinks (120 mA per channel) that can be combined for higher current capability. The device includes adaptive output voltage control based on LED forward voltages to minimize power consumption and supports spread spectrum and external synchronization for EMI reduction.
