Краткое описание:
Highly-integrated 4-channel 120-mA automotive LED driver
Дополнительная информация
The LP8867-Q1 is an automotive high-efficiency LED driver with an integrated boost or SEPIC DC/DC converter. It features four high-precision current sinks that can be combined for higher current capability. The device includes adaptive output voltage control to minimize power consumption by adjusting the voltage based on LED forward voltages. It is designed with spread spectrum and external synchronization to reduce EMI, and includes a power-line FET control for battery bus protection.
