AM20E-C Series DC-DC CONVERTERS 20 watt dc-dc converters • POWER MODULES FOR PCB MOUNTING • SYNCHRONOUS RECTIFIER TOPOLOGY • SURFACE MOUNT TECHNOLOGY • STANDARD 2”x1” PACKAGE AND PINOUT • REMOTE ON/OFF CONTROL ( OPTIONAL) GENERAL DESCRIPTION Our AM20E-C series is a family of cost effective 20W 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 50.8x25.4x10.5mm. The high performance features of our AM20E-C components include short circuit protection with current limit auto recovery, tight line regulation and a high efficiency operation coefficient up to 88%. Six models operate from an input voltage range of 24 & 48VDC then converts it into output voltages of 2.5, 3,3 & 5VDC. 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.
