| 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 -25C to +71C with no derating required. Cooling is done by free air convection. ELECTRICAL SPECIFICATIONS All specifications valid at nominal input voltage, full load and +25C after warm-up time unless otherwise stated.
