UCC28630DR Description

Short technical summary and product information.

The UCC28630DR from Texas Instruments is a high-power flyback controller that utilizes primary-side regulation (PSR) for efficient AC/DC conversion. This controller supports both Continuous Conduction Mode (CCM) and Discontinuous Conduction Mode (DCM) operations, making it versatile for various power supply designs.

 

Key electrical specifications include a maximum duty cycle of 70%, an operating voltage range of 8V to 20V, and a power handling capability of up to 30W. The device operates within a frequency range of 200Hz to 120kHz and features fault protection for overvoltage, overcurrent, and over-temperature conditions. It is designed for surface mount installation in a 7-SOIC package.

 

This controller is suitable for applications requiring efficient power management and isolation. Its features, such as high-voltage startup and X-capacitor discharge, contribute to system reliability and safety. The operating temperature range is from -40°C to 125°C (TJ).
