General Description

The RT8811C is a 2/1 phase synchronous Buck PWM controller which is optimized for high performance graphic microprocessor and computer applications.

The IC integrates a Constant-On-Time (COT) PWM controller, two MOSFET drivers with internal bootstrap diodes, as well as channel current balance and protection functions including Over-Voltage Protection (OVP), Under-Voltage Protection (UVP), current limit, and thermal shutdown into the WQFN-24L 4x4 package.

The RT8811C adopts RDS(ON) current sensing technique.

Key Features

  • external reference input and PWMVID dynamic output voltage control, in which the feedback voltage is regulated and tracks external input reference voltage. Other features include adjustable switching frequency, dynamic phase number control, internal/external soft-start, power good indicator, and enable functions. Features.
  • Dual-Phase PWM Controller.
  • Two Embedded MOSFET Drivers and Embedded Switching Boot Diode.
  • External Reference Input Control.
  • PWM-VID Dynamic Voltage Contro.
