RT8168B Datasheet Dual Single-Phase PWM Controller

Manufacturer: Richtek

Overview: ® RT8168B Dual Single-Phase PWM Controller for CPU and GPU Core Power Supply.

General Description

The RT8168B is a dual single-phase PWM controller with integrated MOSFET drivers, compliant with Intel IMVP7 Pulse Width Modulation Specification to support both CPU core and GPU core power.

This part adopts G-NAVPTM (Green-Native AVP), which is a Richtek proprietary topology derived from finite DC gain compensator in constant ontime control mode.

G-NAVPTM makes this part an easy setting PWM controller to meet all Intel AVP (Active Voltage Positioning) mobile CPU/GPU requirements.
