Description

Description

The STDES-VGAN100F1 is an isolated 80 W quasi-resonant SMPS based on VIPERGAN100.

This controller is a high-voltage converter designed for medium power flyback converters, capable of providing an output power up to 80 W with output current adjustable via PWM interface.

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.

To increase the system efficiency, synchronous rectification based on the SRK1001 at the secondary side is used.

The secondary side also uses an LM2904 operational amplifier to regulate the output voltage and to limit/control the output current.

The STDES-VGAN100F1 design helps designers to develop adapters with a short bill of materials to obtain a cost-effective solution and a fast time to market design.
