RT8870A Dual-Output PWM Controller

The RT8870A is a dual-output PWM controller for AMD SVI mobile CPU power supply. The RT8870A provides a two-phase PWM controller to power the CPU Core (VDD) and a single-phase PWM controller to power the Northbridge portion of the CPU (VDDNB). This part has three integrated MOSFET drivers and is ful.

RT8870A Features

* CCRCOT (Constant Current Ripple Constant On-Time) control with G-NAVPTM (Green-Native AVP), which is a Richtek proprietary topology. The CCRCOT control provides superior output voltage ripple performance over the entire input/output range. G-NAVPTM makes this device an easy setting controller to mee
