EVLVIP17-5WCHG is a 5W SMPS travel battery charger demonstration board based on the VIPER17HN off-line high voltage converter.
The document details the EVLVIP17-5WCHG demonstration board, designed as a travel battery charger for mobile phones, PDAs, and electronic games. It utilizes a flyback topology with the VIPER17HN high voltage converter on the primary side and the TSM1052 CV/CC controller on the secondary side to achieve constant output voltage and current regulation.
| No-load consumption | below 100 mW at high mains |
|---|---|
| Switching frequency | 115 kHz (internally fixed) |
It serves as a 5 W SMPS for use as a travel battery charger for applications such as mobile phones, PDAs and electronic games.
Yes, an important feature of the SMPS is the elimination of the Y1 safety capacitor between the primary and the secondary side.
