Product details

Description

The RT3669EA is a single channel PWM controller with 1 integrated driver and 1 LDO regulator, it is compliant with AMD SVI2 Voltage Regulator Specification to support FP4 GFX power (VDDCR_GFX) and FCH power (VDDCR_FCH_S5).

Features

CCRCOT (Constant Current Ripple Constant On-Time) with G-NAVP (Green-Native AVP), which is Richtek's proprietary topology. G-NAVP makes it an easy setting controller to meet all AMD AVP (Adaptive Voltage Positioning) GFX requirements. The droop is easily programmed by setting the DC gain of the error amplifier. With proper compensation, the load transient response can achieve optimized AVP performance. The controller also uses the interface to issue VOTF Complete and to send digitally encoded vo.
