RT9401C
6Bit VID Reference Generator
General Description
Features
The RT9401C is digital to analog converter which generates
a reference voltage for Intel VR10.x 6-bit VID code
respectively. The part is proposed to pair with a series of
Richteks general purpose PWM controllers dedicated
for the desktop microprocessor core power voltage
regulation. The reference voltage is within 1% high
accuracy.
