STMicroelectronics VIPERGAN50 | Demoboard EVLVIPGAN50FL
EVLVIPGAN50FL: 15 V/50 W isolated flyback with VIPERGAN50
Overview
| Topology | Flyback Converter |
| Input voltage | 90-265 V |
| Output 1 | 15 V / 3.33 A |
| IC revision | 1 |
Description
The EVLVIPGAN50FL evaluation board implements a 15 V-50 W SSR isolated flyback converter developed for general purpose application, operating from 90 to 265 VAC.The reference design is built around the VIPERGAN50, a new advanced offline high-voltage converter by STMicroelectronics, having the following features:Enhanced system reliability is ensured by the built-in soft-start function and by the following set of protections:The EVLVIPGAN50FL is composed of a main board and a daughterboard, whose schematics are shown in Figure 1 and Figure 2 respectively.The main board contains, on the primary side, a diode bridge for double wave rectification, an input pi filter for EMI, a flyback transformer, the VIPERGAN50 and all the related components needed for polarization and features setting; on the secondary side, the output capacitors and the output rectifier, realized by a Power MOSFET driven by a synchronous rectifier for efficiency optimization.
Features
- Universal input mains range: 90 – 265 VAC
- Frequency: 50-60 Hz
- Output voltage: 15 V
- Output current: 3.35 A
- Stand-by mains consumption: < 85 mW at 230 VAC
- Average efficiency: > 90%
- Tight line and load regulation over the entire input and output range
