The intuitive interface guides you through the process step-by-step:
The software’s loop compensation is a starting point. Use a network analyzer (or the voltage injection method) to confirm phase margin >45° and gain margin >10dB. Downloading better software does not replace bench validation.

Other software tools are also available for designing Viper Flyback Converters, including:
With support for flyback, buck, and buck‑boost topologies in both isolated and non‑isolated configurations, VIPer ICs are suitable for everything from small appliance power supplies to industrial auxiliary converters. Whether you need a 4 W, 12 V supply for a smart meter or a 15 V/1.2 A isolated power stage for a home appliance, there is a VIPer device tailored to your requirements.

The software asks for core type. Choose EE25/13/7 (for 24W). It calculates:
: It helps you configure the built-in safety features of the VIPer series, including overvoltage (OVP), overtemperature (OTP), and overload protection (OLP). The software asks for core type
