How to set different output voltages from 10 V to 18 V and how to increase efficiency to 86%

The purpose of this document is to provide information about the STEVAL-ISA081V1 Switch Mode Power Supply (SMPS) demonstration board. The STEVAL-ISA081V1 is an isolated SMPS capable of delivering 12 W output over a wide input voltage range. It is designed to provide a cost-effective and space-saving solution. The STEVAL-ISA081V1 SMPS generates a nominal output voltage of 12 V using primary regulation. The board is based on the VIPer™ 26LD – a monolithic converter integrating a high-voltage MOSFET and a PWM controller. This document contains a basic technical description of the demonstration board (schematic, PCB details and bill of materials) as well as basic measurements (load regulation, efficiency, standby behavior, EMI and thermal behavior data). The last section of this document contains short suggestions on how to set different output voltages in the range of 10 V - 18 V and how to increase the efficiency up to 86%.
