UC2824DW TI PWM Controller | 16-SOIC | 1MHz, 50% Duty Cycle

Product Overview

The UC2824DW from Texas Instruments is a high-performance current-mode PWM controller designed for off-line and DC-to-DC converter applications. Operating at frequencies up to 1 MHz, it provides precise regulation and fast transient response. The device features a 50% maximum duty cycle, making it ideal for single-ended topologies such as forward and flyback converters. Housed in a compact 16-SOIC package, the UC2824DW integrates essential functions including an oscillator, error amplifier, PWM comparator, and output driver, reducing external component count and simplifying design.
