Дополнительная информация
The LM36272 is an integrated dual-channel WLED driver and LCD bias supply designed for small-format LCD panels. It features a backlight boost converter capable of powering two parallel LED strings up to 29V and an LCD bias boost converter that powers a positive LDO and an inverting charge pump for voltages between ±4V and ±6.5V. The device supports 11-bit exponential and linear dimming via I2C or PWM, and provides up to 92% efficiency.
