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:
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.
