概述

The UCC28880EVM-615 evaluation module is an AC/DC buck or buck boost type power supply with direct level shifted feedback.The input accepts a voltage range of 85Vac to 265Vac. The pre-set output voltage is set to ~12.5V (typ). Note: The output voltage is referenced to the positive DC input (HVDC node), not to the RTN node. In buck configuration the DC OUTPUT voltage on P2 is negative with respect to HVDC, and in buck-boost configuration the DC OUTPUT voltage on P2 is positive with respect to HVDC. The evaluation module uses the UCC28880 low quiescent current switcher IC. This devices integrates a 700V FET and controller into one SOIC7 package. The device also features a high voltage current source, enabling start-up and operation directly from the rectified mains voltage. The low quiescent current of the device enables very high efficiency in non isolated high side buck low power converters. The device is also protected from failure conditions with thermal shutdown, under voltage lockout, soft start and overload protection. The UCC28880 is suited for use in non isolated off line systems. Typical applications include Home Appliances, White Goods, E Metering, Home Automation and LED Lighting.
