Product overview
Description
The STDES-VPGAN100F is an isolated 100 W quasi-resonant SMPS based on VIPERGAN100.
This controller is a high voltage converter designed for medium power flyback converters. It can provide an output power up to 100 W in the European range or with a PFC in the front-end.
The device offers protection features that considerably increase the end-product´s safety and reliability: output voltage protection, overtemperature protection (OTP), overload protection (OLP), brown-in/out protection. All these protections are in auto restart mode.
A PFC based on L6562A reduces the AC input current distortion in a wide-range-mains operation with extremely low THD.
Synchronous rectification based on the SRK1000B at secondary side is used to increase the system efficiency.
The secondary side uses an LM2904D operational amplifier to regulate the output voltage and to limit the maximum output current.
The STDES-VPGAN100F helps designers to develop adapters with a short bill of materials to obtain a cost-effective solution and a fast time to market design.
