| AM20E-C Series 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) DC-DC CONVERTERS 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 -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.
