TI UCC28880DR
Non-isolated AC/DC converter designed for high voltage switching applications
UCC28880DR 概要
The UCC28880DR is a resonant mode power supply controller designed for high-density offline AC-DC power supplies. It operates at a fixed frequency of 100 kHz and features a wide input voltage range of 85 VAC to 265 VAC. The controller includes an internal 700 V MOSFET for primary-side regulation, eliminating the need for an optocoupler and secondary-side control circuitry.The UCC28880DR offers a high level of integration, incorporating a high-voltage startup regulator, a current sense amplifier, and a high-voltage gate driver. This integration helps reduce component count and overall system cost while improving efficiency and reliability. The device also includes comprehensive protection features such as overcurrent protection, overvoltage protection, and overtemperature protection.
