UCC2803DTR TI PWM Controller | 8-SOIC | 1MHz, 4.1V UVLO

Product Overview

The UCC2803DTR from Texas Instruments is a high-performance, low-power BiCMOS current-mode PWM controller designed for off-line and DC-to-DC converter applications. It operates at a fixed frequency up to 1 MHz, with a startup current of less than 1 mA and a low operating current of 12 mA. The device features a 4.1V under-voltage lockout (UVLO) threshold, making it suitable for battery-powered systems. Housed in an 8-pin SOIC package, it offers a compact solution for power supply designs.
