1 / 2 page 51 VISIT US AT WWW.AIMTEC.CA AM3TW Series • 24-PIN DIP PACKAGE • LOW PROFILE METAL PACKAGE • HIGH EFFICIENCY UP TO 79% • WIDE 4:1 INPUT RANGE • INPUT/OUTPUT ISOLATION: 1500 & 3500VDC • OPERATING TEMPERATURE: -40°C ... +85°C • PIN-COMPATIBLE WITH MULTIPLE MANUFACTURERS • CONTINUOUS SHORT CIRCUIT PROTECTION GENERAL DESCRIPTION Our AM3TW series is a family of cost effective 3W single and dual output DC-DC converters. These converters combine nickel-coated copper package in a 24-pin DIP compatible case with high perform- ance features such as 1500 & 3500VDC input/output isolation volt- age, continuous short circuit protection with automatic restart and tight line / load regulation. Wide range devices operate over 4:1 input voltage range providing stable output voltage. Devices are encapsulated using flame retardant resin. Input voltages of 24 & 48VDC with output voltages of 3.3, 5, 7.2, 9, 12, 15, 18, 24, ±3.3, ±5, ±7.2, ±9, ±12, ±15, ±18 & ±24VDC. High performance features include high efficiency operation up to 79% and output voltage accuracy of ±1% maximum. All models are packaged in a low profile 31.75x20.32x10.16mm 24 pin DIP nickel-coated copper case. Operation is specified over the full operating temperature range of -40°C to +85°C with no derating required. Cooling is by free-air convection.
