STEVAL-ISA021V1: 10W, 12V @ 840mA, 85 ~ 265VAC

Summary

The VIPer22A off-line SMPS primary switcher combines a dedicated current mode PWM controller with a high voltage Power MOSFET on the same silicon chip and its switching frequency is internally fixed at 60 kHz. The feedback path of the power supply includes an optocoupler for secondary regulation and galvanic isolation between primary and secondary sides. The output voltage is regulated at 12V with a maximum output current of 0.84A, resulting in a maximum output power of 10W.
