0P - RT8813A – Richtek - WQFN-24

Multi-Phase PWM Controller with PWM-VID Reference

کنترل کننده چند فاز از   (PWM ) با  (PWM ) مرجع

General Description

The RT8813A is a 3/2/1 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 RT8813A adopts RDS(ON) current sensing technique. Current limit is accomplished through continuous inductorcurrent- sense, while RDS(ON) current sensing is used for accurate channel current balance. Using the method of current sampling utilizes the best advantages of each technique


The RT8813A 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
