Description
The STEVAL-ISA111V1 demonstration board is a 12 V, 1 A power supply set in non-isolated flyback topology using the VIPER26HN, the new offline high voltage converter by STMicroelectronics.
The features include an 800 V avalanche rugged power section, PWM operation at 115 kHz with frequency jittering for lower EMI, current limiting with adjustable set point, onboard soft-start, a safe auto-restart after a fault condition and a low standby power. The protections include thermal shutdown with hysteresis, delayed overload protection, and open loop failure protection.
Features
◾ Universal input mains range:
– input voltage 90 - 264 VAC
– frequency 45 - 65 Hz
◾ Single-output voltage: 12 V at 1 A continuous
operation
◾ Standby mains consumption: < 30 mW at
230 VAC
◾ Average efficiency: > 80%
◾ Fully protected against faults (overload,
feedback disconnection and overheating)
◾ EMI: according to EN55022-Class-B
◾ RoHS compliant
