Product overview
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:
- 650 V PowerGaN with embedded senseFET (Si) and HV startup;
- QR operation with dynamic blanking time and adjustable valley synchronization delay functions, to maximize efficiency at any input line and load condition;
- Valley-lock to ensure constant valley skipping;
- Input voltage feedforward compensation for mains-independent OPP intervention;
- Adaptive burst mode for advanced power management in light load conditions;
- Frequency jittering for EMI suppression.
Enhanced system reliability is ensured by the built-in soft-start function and by the following set of protections:
- Input OVP (settable);
- Brown-in and brown-out (settable);
- Output OVP (settable);
- Output overload;
- OCP LEB;
- Embedded thermal shutdown.
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.
