STEVAL-ISA112V1

Wide range non-isolated flyback demonstration board, single-output

12 V/4 W based on the VIPER06HN

Data brief

Features

– frequency 45 - 65 Hz

continuous operation

Description

The STEVAL-ISA112V1 demonstration board

implements a 4 W single-output wide range mains

power supply to be used in applications such as

white goods, smaller home appliances, home

automation, LED driver, etc.

The board uses the new VIPER06HN, a new

offline high voltage converter from the VIPerPlus

family by STMicroelectronics. The VIPER06 is

specifically designed for fixed frequency flyback

converters, combining a high-performance low

voltage PWM controller chip and a max. 32

Ω

RDS(on), 800 V BV(DSS), avalanche-rugged

Power MOSFET in the same package.

The application is optimized for less than 30 mW

standby consumption and meets the EPA 2.0

limits, therefore helping to meet the most stringent

energy saving requirements.

The STEVAL-ISA112V1 demonstration board

implements several forms of protection that

considerably increase end-product safety and

reliability: overload protection, feedback

disconnection, thermal shutdown.
