STEVAL-ISA129V1

16 V - 280 mA non isolated off-line high voltage converter based on

the VIPer16

Data brief

Features

50 mV

• RoHS compliant

Description

The STEVAL-ISA129V1 demonstration board is a

16 V - 280 mA application set in non isolated

flyback topology using the VIPer16, a new off-line

high voltage converter by STMicroelectronics.

The VIPer16 features an 800 V avalanche rugged

power section, PWM operation at 115 kHz with

frequency jittering for lower EMI, limiting current

with adjustable set point, on-board soft-start, and

safe auto-restart after a fault condition.

Moreover, the VIPer16 can work with or without

the auxiliary winding. In the former case, it can

reach very low standby consumption (< 50 mW at

an internal current generator, thus eliminating the

cost of the transformer auxiliary winding.

• Protection features available include thermal

shutdown with hysteresis and delayed

overload protection.
