3 Description

The UCC28C5x-Q1 family of devices are high

performance current-mode PWM controllers helping

both Si and SiC MOSFETs applications. The

UCC28C5x-Q1 family has six VDD UVLO options,

with VDD abs max extended to 30 V, and reduced

startup and operation currents. The UCC28C5x-Q1

family provides improved version of UCC28C4x-

Q1. The table below shows the comparison. The

UCC28C5x-Q1 family is offered in the 8-pin SOIC (D)

package.
