AM20U-C Series
20 watt dc-dc converters
POWER MODULES FOR PCB MOUNTING
V-OUT TRIM AND ON/OFF CONTROL
REGULATED OUTPUT
LOW RIPPLE & NOISE
GENERAL DESCRIPTION
OurAM20U-C series is a family of cost effective 20W single, dual
& tripleoutputDC-DCconverters.Theseconvertersareshieldedon
all six sides and encapsulated with a nickel-coated copper with a
non-conductive base and dimensions of 50.8x50.8x10.8mm. The
high performance features of our AM20U-C components include
short circuit protection with hiccup auto recovery, tight line regula-
tion and a high efficiency operation coefficient up to 82%.
Thirty models operate from an input voltage range of 12,
24 & 48VDC producing single, dual or triple output volt-
ages. The normal operation is specified over the full
operating temperature range of -25°C to +71°C with no
derating required. Cooling is done by free air convection.
