Category: RT IC Richtek
Description
The RT8813CGQW RT8813C 27= Marking 27=IC is a 3/2/1 phase synchronous buck PWM controller optimized for high-performance graphics processors and computing applications. Housed in a compact WQFN-24L 4x4 package, it integrates a Constant-On-Time (COT) PWM controller, two MOSFET drivers with internal bootstrap diodes, and comprehensive protection features including over-voltage protection (OVP), under-voltage protection (UVP), current limiting, and thermal shutdown.
Specification
The RT8813CGQW RT8813C 27= Marking 27=IC employs RDS(ON) current sensing for precise channel current balancing combined with continuous inductor current sensing for accurate current limiting, leveraging the advantages of both techniques. Key features include external reference input with PWMVID dynamic voltage control for tracking external reference voltages, adjustable switching frequency, dynamic phase control, internal/external soft-start options, power good indicator, and enable functions for flexible system integration.
