STEVAL-ISA005V1
Features
1.8W buck topology power supply evaluation board
with VIPer12AS
Data Brief
■ Switch mode general purpose power supply
■ Input: 85 to 264Vac @ 50/60Hz
■ Output: 15V, 100mA @ 50/60Hz
■ Output power (pick): 1.6W
■ Second output through linear regulator: 5V / 60
or 20mA
Description
This evaluation board is an auxiliary power supply
based on the VIPer12AS monolithic device with
rather low output power required. It is a buck
(step-down) converter with a positive output
voltage referenced to the common ground based
on the monolithic device VIPer12AS, which is a
device that incorporates the PWM controller
together with the vertical Power MOSFET switch
in a SO-8 package.
