UCC28C44 General Description

The UCC28C44's voltage-mode PWM controller is particularly well-suited for off-line power supplies, offering a versatile range of applications due to its internal oscillator that operates at a fixed frequency of 100 kHz. This precision control over the duty cycle, thanks to its proprietary current mode architecture, enables the device to support high switching frequencies up to 1 MHz

Key Features
