RT9401B

RT9401A/B 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 z RT9401A Support 5bit DAC Voltage Conforming to Intel VRD10.x VID Table z RT9401B Support 5bit DAC Voltage Conforming to AMD K8 VID Table z 1% High Accuracy of VREF z Small Footprint Package of SOT-23-8 z RoHS Compliant and 100% Lead (Pb)-Free package of SOT-23-8.
