STMicroelectronics VIPer01 | Demoboard Steval-ISA177V1
5 V, 0.85 A flyback converter using VIPer™ Plus – VIPer01
Overview
| Topology | Flyback Converter |
| Input voltage | 85-265 V |
| Output 1 | 5 V / 0.8 A |
| IC revision | V1 |
Description
The STEVAL-ISA177V1 evaluation board implements a wide-range converter in flyback non isolated topology, delivering 0.85 A on a 5 V output for general purpose applications.The core of the application is the new VIPer01 offline high voltage converter from the VIPerPlus range that intelligently integrates an 800 V rugged power MOSFET with PWM current-mode control.The main characteristics of the evaluation board are its single layer, small size with minimal BOM, high efficiency and low standby consumption.
Features
- Universal AC main input voltage range: 85VAC to 265VAC
- Output range: 5 V / 0.85 A
- Rated output power: 4.25 W
- Input power in standby @ 230 VAC: < 9 mW
- Active mode efficiency: > 74%
- EMI: according to EN55022-Class-B
- RoHS compliant
