UCC28C40DGKR TI PWM Controller | 8-VSSOP | 1MHz, 50% Duty Cycle

Product Overview

The UCC28C40DGKR is a high-performance current-mode PWM controller from Texas Instruments, designed for off-line and DC-to-DC power conversion applications. It features a 1MHz maximum switching frequency, 50% maximum duty cycle, and operates from a supply voltage range of 7V to 15V. Housed in an 8-VSSOP package, this device offers low startup current (0.1mA typical) and low operating current (1.5mA typical), making it ideal for energy-efficient designs.

Detailed Technical Specifications

Key Features

• Current-mode control for improved transient response and simplified loop compensation
