EVLVIP17-5WCHG, 5W Low Standby Consumption Battery Charger Demonstration Board based on the VIPER17HN

EVLVIP17-5WCHG, Demonstration Board is a 5W SMPS for use as a travel battery charger for applications such as mobile phones, PDAs and electronic games. The purpose of the board is to demonstrate the performance of the VIPER17HN off-line high voltage converter. Thanks to its low consumption and other features, good electrical performance is achieved. To obtain constant output voltage and current regulation (CV/CC), the TSM1052 CV/CC controller is used on the secondary side. This TSM1052 is well-suited for this type of application, offering very low current consumption in a very small package (SOT23-6L). Another important feature of the SMPS is the elimination of the Y1 safety capacitor between the primary and the secondary side
