General Description

The RT8809A/B is a dual-phase synchronous buck PWM controller with integrated drivers which are optimized for high performance graphic microprocessor and puter applications.

The IC integrates a G-NAVPTM PWM controller, two 12V MOSFET drivers with internal bootstrap diodes, as well as output current monitoring and protection functions into the WQFN-24L 4x4 package.

The RT8809A/B adopts DCR and RDS(ON) current sensing.

Key Features

  • a one-bit VID control operation in which the feedback voltage is regulated and tracks external input reference voltage. Other features include, adjustable operating frequency, external compensation, and enable/shutdown functions.
