The UCC38085D is a versatile Pulse Width Modulation (PWM) controller integrated circuit (IC) designed and manufactured by Texas Instruments. Specifically engineered for efficient power conversion and management, this device is a key component in switch-mode power supplies (SMPS), often used in applications such as consumer electronics, telecommunication equipment, and industrial systems.

Key Features

• Peak Current Mode Control: The UCC38085D uses peak current mode control to provide excellent transient response and simplified loop compensation.
• Wide Operating Range: With an operating voltage range of 8.5V to 14.5V, it can accommodate a broad spectrum of power supply designs.
• Adjustable Switching Frequency: Users can set the switching frequency anywhere from 100 kHz to 1 MHz, allowing flexibility in the design of the power supply.
• Internal Slope Compensation: The IC includes built-in slope compensation to ensure stable operation for duty cycles above 50%.
• Soft Start Feature: The soft start functionality prevents inrush current at startup, enhancing the reliability of the power supply.
• Shutdown Capability: The UCC38085D can be shut down through a dedicated pin, which reduces the supply current to 1 µA, enabling power-saving modes.

Applications

• AC/DC Power Supplies
• Isolated and Non-Isolated Power Supplies
• DC/DC Converters
• Telecom and Networking Power Systems
