Description
The STEVAL-ISA116V1 demonstration board
implements a double-output power supply set in
buck topology using the VIPER26LD, a new off-
line 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 auto-
restart mode.
