UCC2805PW TI PWM Controller | 8-TSSOP | 1MHz, 4.1V UVLO

Product Overview

The UCC2805PW from Texas Instruments is a high-performance BiCMOS PWM controller designed for off-line and DC-to-DC power supply applications. It features a 1MHz oscillator, low startup current (100µA typical), and a 4.1V under-voltage lockout (UVLO) threshold. The device is housed in a compact 8-pin TSSOP package, making it ideal for space-constrained designs.
