STEVAL-ISA135V1 Datasheet, PDF (1/4 Pages) STMicroelectronics – Thermal shutdown with hysteresis

STEVAL-ISA135V1
4 W, 12 V output, isolated flyback converter using VIPer™ Plus -
VIPER06HS
Data brief
Description
The STEVAL-ISA135V1 is a 12 V - 4 W power
supply in isolated flyback topology based on the
VIPer06HS, a new offline high voltage converter
having, as main features: 800 V avalanche
rugged power section, PWM operation at 115
kHz with frequency jittering for lower EMI, cycle-
by-cycle current limit with adjustable set point,
on-board soft-start and safe auto-restart after a
fault condition.
Features
