The EVLVIP17-5WCHG demonstration board is a 5 W 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. Another important feature of the SMPS is the elimination of the Y1 safety capacitor between the primary and the secondary side.
