STEVAL-ISA114V1
5 V, 160 mA non-isolated buck converter using VIPer™ Plus -
VIPER06XS
Data brief
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
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, on-
board 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.
