Краткое описание:
45-V LED backlight driver with four channels 120-mA output
Дополнительная информация
The TPS92381 is a highly integrated, high-output power LED driver with an integrated boost/SEPIC DC/DC converter. It features four high-precision current sinks that can be combined for higher current capability. The DC-DC converter uses adaptive output voltage control based on LED forward voltage to minimize power consumption. It supports a wide input voltage range from 4.5V to 40V, switching frequencies from 300kHz to 2.2MHz, and includes spread spectrum for reduced EMI.
