| 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 DC-DC CONVERTERS GENERAL DESCRIPTION Our AM20U-C series is a family of cost effective 20W single, dual & triple 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 50.8x50.8x10.8mm. The high performance features of our AM20U-C components include short circuit protection with hiccup auto recovery, tight line regulation 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 voltages. 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.
