 DC/DC converter

Power solutions provider Aimtec has recently unveiled a new 5 watt DC/DC converter series. The AM5E-FZ operates at -55 °C to 85 °C without derating, to support all outdoor applications, including those at risk of being exposed to severe weather conditions. The Aimtec's DC/DC converter has been designed for applications in solar inverters, smart meters, transmission equipment, security systems, traffic and advertising signage.

AM5E-FZ�series offers 21 models with a choice of wide, 2:1 input ranging from 9 to 72VDC, stepping down to single or dual output ranges of 3.3 to 15VDC, at efficiency rates as high as 87 per cent. Design engineers will also appreciate the tight line and load regulation of 0.5 per cent (single output models), as it ensures that stable voltages are delivered throughout the operating range, under all loading conditions.

With a fixed switching frequency of 300kHz, designs using the�AM5E-FZ�series benefits from a simplified filter design process, which also translates to smaller, more compact filters – an important consideration for many applications.

Other design value features include I/O isolation of 1.5KVDC, continuous short circuit protection, over load and voltage protection, all housed in a compact 2"x1" case which stands only 0.40" high.

Datasheet for the AM5E-FZ can be found here.
