RT9401B - 5Bit VID Reference Generator

Download the RT9401B datasheet PDF. This datasheet also covers the RT9401A variant, as both devices belong to the same 5bit vid reference generator family and are provided as variant models within a single manufacturer datasheet.

Key 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 z RT9401A Support 5bit DAC Voltage Conforming to Intel VRD10.x VID Table z RT9401B Support 5bit DAC Voltage Conformi.
