AM20U-C Series DC-DC CONVERTERS 20 watt dc-dc converters • POWER MODULES FOR PCB MOUNTING • REGULATED OUTPUT • V-OUT TRIM AND ON/OFF CONTROL • LOW RIPPLE & NOISE 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 -25°C to +71°C with no derating required. Cooling is done by free air convection.
