5Bit VID Reference Generator
General Description
Features
The RT9401A/B are digital to analog converters which generate a reference voltage for Intel VR10.x/AMD K8 5-bit VID code respectively. The parts are proposed to pair with a series of RichTek’ s general purpose PWM controllers dedicated for the desktop microprocessor core power voltage regulation. The reference voltage is within 1% high accuracy. These parts use a small footprint
