The RT8870A is a dual-output PWM controller for AMD SVI mobile CPU power supply.

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 meet the droop requirement for all AMD mobile CPUs. The droop is easily programmed by setting the DC gain of the error amplifier. With proper compensation, the load transient response can achieve optimiz.
