What is UCC28C42DGKR used for?

It is intended for switch-mode power supplies, including offline flyback and other isolated or non-isolated AC-DC and DC-DC converter designs.

What should engineers review before using UCC28C42DGKR?

Review the 20 V VDD absolute maximum rating, the 14.5 V typical UVLO turn-on threshold, current-sense noise filtering, slope compensation when duty cycle exceeds 50%, and local VDD/VREF bypassing.

What is the pinout of UCC28C42DGKR?

Use the UCC28C42DGKR datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about UCC28C42DGKR pinout to locate pins, power rails, and interface signals before layout.

AI summary

UCC28C42DGKR is an offline-oriented current-mode PWM controller in VSSOP-8 with 14.5 V/9 V UVLO, a 5 V reference, fast cycle-by-cycle current limiting, and a 1 A peak MOSFET gate driver.

Best for

Offline current-mode flyback converters
Fixed-frequency MOSFET power stages
Compact VSSOP controller implementations

Avoid if

The available bias supply cannot exceed the UVLO turn-on threshold
VDD transients cannot be controlled below 20 V
A controller with integrated startup or advanced protection features is required
