40 watt dc-dc converters
• POWER MODULES FOR PCB MOUNTING
• SIX-SIDED CONTINUOUS SHIELD
• HIGH EFFICIENCY
• STANDARD PACKAGE
OurAM40K-C series is a family of cost effective 40W single out-
put DC-DC converters. These converters are shielded on all six
sides and encapsulated with a nickel-coated copper with a non-con-
ductive base and dimensions of 50.8x40.64x10.8mm. The high
performance features of our AM40K-C components include short
circuit protection with hiccup auto recovery, tight line regulation
and a high efficiency operation coefficient up to 89%.
Seven models operate from an input voltage of 48VDC
producing output voltages of 1.8, 2.5, 3.3, 5, 12, 15 &
24VDC. 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.
All specifications valid at nominal input voltage, full load and +25°C after warm-up time unless otherwise stated.
