VIPer12AS ,SO-8 SMD Package, 9V to 38V Input, Low Power Off-Line SMPS Primary Switcher

The VIPer12AS is a high-efficiency low-power off-line SMPS primary switcher in an SMD SO-8 package. With its integrated PWM controller and high-voltage Power MOSFET, the VIPer12AS offers superior performance in power conversion. It is designed to work with input voltages from 9V to 38V and includes built-in protections such as over-temperature, overcurrent, and overvoltage protection with autorestart.

This switcher is ideal for low power applications, providing up to 8W of output power for European voltage ranges (195-265VAC) and 5W for US/Wide voltage ranges (85-265VAC). Its small surface-mount design ensures high efficiency while saving board space in compact applications like battery chargers, motor control, and auxiliary supplies.
