STEVAL-ISA010V1
Ultra wide range dual output back converter demonstration board
based on the VIPER16
Data brief
Features
■ Input voltage Vin: 85 - 500 VAC (f: 45 - 66 Hz)
■ Output voltages:
– V1= 12 V 10%
– V2= 5 V 4%
■ Output current: 150 mA total (5 V and 12 V
output) output current for full input voltage
range
■ Standby: 96 mW at 230 VAC
■ Short-circuit protection
STEVAL-ISA010V1
■ PCB type and size:
– FR4, single side 70 µm
– dim.: 27 x 45 mm
after any fault condition removal. Burst mode
operation at light load combined with the very low
consumption of the device helps to meet standby
energy-saving regulations.
■ Isolation: non isolated - N connected to output
GND
The significant benefit of this new chip derives
from the jitter of the switching frequency and the
possibility to supply the chip directly from the DC
HV bus, so auxiliary supply is not mandatory.
■ EMI: In accordance with EN55022 - class B
■ EMC: surge - IEC 61000-4-5 - 2 kV
■ EMC: burst - IEC 61000-4-4 - 8 kV
■ RoHS compliant
The VIPER16 is suitable for flyback or buck
topologies and thanks to an internal self-supply
circuit it does not require an auxiliary supply.
Description
This demonstration board based on VIPER16 is
designed as an example of a simple non-isolated
auxiliary power supply for a range of input
voltages from 85 VAC to 500 VAC.
There is an ever-increasing demand for small
power supplies capable of working without
voltage range limitations, even at nominal levels
of 400 VAC and 415 VAC, respectively. The real
voltage level can reach 500 VAC (415 V + 20%).
The major markets for this type of SMPS are
home appliances and metering.
The VIPER16 device includes an 800 V rugged
power switch, a PWM controller, programmable
overcurrent, overvoltage, overload, a hysteretic
thermal protection, soft-start and safe auto-restart
