AM8TW-C Series DC-DC CONVERTERS 8 watt dc-dc converters • 24PIN DIP PACKAGE • PLASTIC ENCAPSULATED CASE • POWER MODULES FOR PCB MOUNTING • 4:1 WIDE INPUT RANGE • REGULATED OUTPUT • LOW RIPPLE & NOISE • OPERATING TEMPERATURE : -25 … +71°C GENERAL DESCRIPTION Our AM8TW-C series is a family of cost effective 8W single and dual output DC-DC converters. These converters are shielded on all six sides and aluminum encapsulated, have a non-conductive base and retain an anodized black DIP24 compatible plastic case and dimensions of 31.8x20.3x10.2mm. The high performance features of our AM8TW-C components include short circuit protection with current limit auto recovery, tight line regulation and a high efficiency operation coefficient up to 82%. These wide range devices operate over 4:1 input voltage range, providing a continuously stable output voltage. Sixteen models operate from an input voltage range of 24 & 48VDC producing output voltages of 3,3, 5, 12, 15, 24, ±5, ±12 & ±15VDC. 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.
