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.
