AMPSS
AM80A Performance Series DC-DC Converters
Introduction
The single output AM80A is an isolated, single output
DC to DC converter module, providing up to 252W
output with a maximum baseplate operating temperature
of 100°C with no derating. The AM80A features full
safety isolated low voltage secondary side control and
Astec Linear Programming (ALP™) for convenient
adjustment of the module's parameters.
The dual output AM80A provides two outputs, 3.3V
and 5.0V.
