AM40U-4812SC

AM40U-C Series 40 watt dc-dc converters • • • POWER MODULES FOR PCB MOUNTING V-OUT TRIM AND ON/OFF CONTROL REGULATED OUTPUT • • LOW RIPPLE & NOISE SYNCHRONOUS RECTIFIER TOPOLOGY GENERAL DESCRIPTION Our AM40U-C series is a family of cost effective 40W single output DC-DC converters. These converters are shielded on all six sides and encapsulated with a nickel-coated copper with a non-conductive base and dimensions of 50.8x40.64x10.8mm. The high performance features of our AM40U-C components include short circuit protection with hiccup auto recovery, tight line regulation and a high efficiency operation coefficient up to 88%. 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.
