General Description

The AS3681 is a highly-integrated, ultra-flexible CMOS Power- and Lighting Management Unit to supply power to LCD- and camera-modules in mobile telephones, and other 1-cell Li+ or 3-cell NIMH powered devices. The AS3681 in corporates one low-power,low-dropout regulator(LDO), one Step Up DC/DC Converter for white backlight LEDs, one high-power Charge Pump for camera

flash LEDs, oneAnalog-to-DigitalConverter,support for up to 11 current sinks, a serial interface,and control logic all onto a single die.

Noise (< 30µVrms from 100Hz to 100kHz)

Line/load Regulation (<1mV Static and <20mV Transient)

Power Supply Rejection (>70dB@1kHz)

Ultra-Low Power Consumption (1µA Shutdown, 6µA Standby)
