STMicroelectronics HVLED001B | Demoboard EVAL-PSR01B-35W
35 W wide input range flyback converter using HVLED001B quasi resonant flyback controller and STF10LN80K5
Overview
| Topology | Flyback Converter |
| Input voltage | 90-265 V |
| Output 1 | 48 V / 0.73 A |
| IC revision | 1 |
Description
The EVAL-PSR01B-35W is intended to provide a stable and insulated 48 V voltage bus suitable to supply secondary side circuitry for a total output power of 35 W when a wide range of input voltages is applied at its input. A very high power factor is obtained thanks to HVLED001B features. Input voltage variations, excessive input voltage (overvoltage like surge or bursts) or very low input voltages are managed by some of the HVLED001B protections, improving the reliability of the application.
Features
- Input voltage: Vin: 90 - 265 Vrms, f: 45-66 Hz
- Output voltage: 48 V / 730 mA
- High power factor, low THD
- No-load: better than 150 mW @ 230 Vin
- Average full load efficiency: 90%
- Short-circuit protection with auto restart
- Safety: Acc. to EN60065
- EMI: Acc. to EN55022 - conducted emissions
