STEVAL-ISA116V1

STEVAL-ISA116V1 5 W, 2-output wide-range buck converter based on the VIPER26LD Data brief Features ■ Universal input mains range: – input voltage: 80 - 280 VAC – frequency: 45 - 65 Hz ■ Double-output voltage: – 16 V @ 0.3 A continuous operation – 5 V through LDO ■ Standby mains consumption: < 100 mW @ 265 VAC ■ Fully protected against faults (overload, feedback disconnection and overheating) ■ EMI: according to EN55022-Class-B ■ RoHS compliant Description The STEVAL-ISA116V1 demonstration board implements a double-output power supply set in buck topology using the VIPER26LD, a new offline high voltage converter by STMicroelectronics. The features of the device include an 800 V avalanche-rugged power section, PWM operation at 60 kHz with frequency jittering for lower EMI, current limiting with adjustable set point, on-board soft-start, safe auto-restart after a fault condition and low standby power consumption. The protection features include thermal shutdown with hysteresis, delayed overload protection and open loop failure protection. All protection is autorestart mode.
