This document is a technical brief for STEVAL-ISA035V1 non-isolated offline power supply demonstration board, which introduces the features, usage and other information of the board.
The STEVAL-ISA035V1 is a non-isolated offline power supply demonstration board designed to furnish low output power for applications such as microcontrollers, LED displays, and relays. It is based on the VIPER22A-E controller and features a low component count with integrated thermal overload and short-circuit protection.
| Input voltage range | 85 Vac to 264 Vac |
|---|---|
| Input voltage frequency | 50/60 Hz |
| No-load consumption | around 200 mw |
| Efficiency | 70% to 80% at full load |
| Output voltage range | 10 V to 35 V |
The board can use the VIPER12A-E or the VIPER22A-E, which are pin-for-pin compatible.
