STMicroelectronics Buck Converter for VIPER26LD

The STEVAL-ISA116V1 demonstration board implements a double-output power supply set in step-down (buck) topology using the VIPER26LD, an energy saving VIPerPlus, 12W high voltage converter with direct feedback.
The VIPER26LD features include an 800V avalanche-rugged power section, PWM operation at 60kHz 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.

Universal input mains voltage 80 to 280VAC at 45-65Hz
Dual-output voltage; 16V @ 300mA continuous operation and 5V through LDO Regulator
Standby power consumption less than 100mW @ 265VAC
Fully protected against faults (overload, feedback disconnection and over-heating)
EMI: according to EN55022-Class-B
