德州仪器 UCC28711EVM-160 评估模块 (UCC28711 评估模块) 帮助设计者评估UCC28711的性能,UCC28711反激式电源控制器在不使用光耦合器的情况下可提供隔离输出恒定电压 (CV) 和恒定电流 (CC) 输出稳压。
The 5W EVM is used for evaluating an off line adapter for USB applications. It converts a 90V to 265V RMS input voltage down to 5V DC, with a 1A current limit for USB adapter applications. It is intended for evaluation purposes and is not intended to be an end product. 特性
<10mW no load power
Primary Side Regulation (PSR) eliminates opto-coupler
+/- 5% Voltage & Current Regulation
100 KHz max switching frequency enables high power density charger designs
Quasi-resonant valley switching operation for highest overall efficiency
Wide VDD range (35V) allows small bias capacitor
Drive Output for MOSFET - Protection Functions: Over Voltage, Low Line, Over Current
