UCC28C45DR TI PWM Controller | 8-SOIC | 1MHz, 48% Duty Cycle

Product Overview

The UCC28C45DR from Texas Instruments is a high-performance, current-mode PWM controller designed for a wide range of power supply applications. Housed in an 8-pin SOIC package, this device offers precise control and reliable operation for DC-DC converters, off-line power supplies, and other power conversion systems. With a maximum switching frequency of 1 MHz and a duty cycle range up to 48%, the UCC28C45DR provides efficient power management with minimal external components.

Detailed Technical Specifications

Key Features

• Current-mode control for improved transient response and simplified loop compensation
• High-frequency operation up to 1 MHz reduces transformer and filter size
• Internal soft-start minimizes inrush current during startup
• Under-voltage lockout (UVLO) with hysteresis ensures reliable operation
• Low startup current (0.5 mA typical) for energy-efficient designs
• Totem-pole output driver with 1 A peak current capability
• Trimmed oscillator discharge current for precise dead-time control

Target Applications

• Telecom power supplies (e.g., 5G base station power modules)
• Automotive electronics (e.g., dashboard power supply, infotainment systems)
• Industrial power converters (e.g., PLC power supplies, motor drives)
• Consumer electronics (e.g., LED TV power boards, laptop adapters)
• Off-line AC-DC converters for home appliances
