RT9401D
5-Bit VID Reference Generator
General Description
The RT9401D is a digital to analog converter which
generate a reference voltage for AMD Mars 5-bit VID code.
The IC is 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. The RT9401D
is available in SOT-23-8 package.
