AC-DC power supply module
Datasheet − production data
Description
ST's power modules are highly integrated, high
efficiency switch mode converters. The SPAC265
family of converters includes isolated AC-DC,
single output modules. The module can operate in
accordance with the European input voltage
range. It's a turnkey drop-in solution requiring no
additional external circuitry. This specific version
performs 8 W peak output power at 5 Vdc. It can
support 800 mA output current in continuous
mode, and can withstand 1.75 A peak 25% of the
time.
