Description

The STEVAL-ISA114V1 evaluation board

describes a 5 V- 0.15 A power supply set in buck

topology with the VIPer06XS, a new off-line high

voltage converter by STMicroelectronics,

specifically developed for non-isolated SMPS.

The features of the device include an 800 V

avalanche rugged power section, PWM operation

at 30 kHz with frequency jittering for lower EMI,

limiting current with adjustable set point, onboard soft-start, safe auto-restart after a fault

condition and low standby power consumption.

The available protection includes a thermal

shutdown with hysteresis, delayed overload

protection and open loop failure protection. All

protection is auto-restart mode.

Features

 Universal input mains range:

 input voltage: 90 - 264 VAC

 frequency: 45 - 65 Hz

 Single-output voltage:

 5 V @ 0.16 A continuous operation

 Fully protected against faults (overload,

feedback disconnection and overheating)

 EMI: according to EN55022-Class-B

 RoHS compliant
