SN18400P
SN18400P is TFT LCD Integrated Power Module manufactured by Richtek.
Description
The SN18400P is an I2C interface programmable power management IC. The IC includes two synchronous AVDD/VGH boost converter, a two RESET function, a low dropout LDO, a VGL charge pump, a high performance V with 7-bit Calibrator, 2-CH gamma, and a voltage detector. With available in a UQFN-28L 3.5x3.5 (FC) package, this device is suitable for TFT-LCD panel. The IC can operate from 2.5V to 5V input voltages. High frequency operation allows a pact PCB circuit area with small inductors and capacitor. Current-limit functions are provided for all internal-switch converters, and output-fault shutdown protects all converters against output-fault conditions. Programmable soft-start functions for all output voltage to limit input inrush current during startup.
