20 to 60W DC/DC converters integrate heatsink in compact package

October 10, 2012 // By Julien Happich
Peak electronics' PO/HS series of high power DC/DC converters integrate a heatsink that can be specified to remove the heat according to the needs of the application.

The heatsink, which is mounted directly on the converter package, is made of aluminium and, depending on the model, weighs an additional 16 g, 19 g or 128 g (without the converter).

The PO/HS series of converters ranges from 20-watt DC/DC converters housed in a 25.4x50.8mm package to 60-watt DC/DC converters housed in a 50.8x50.8mm package. All models are available with a wide 4:1 input voltage range of 9‑36 V or 18‑72 V. The converters deliver output voltages of optionally 1.8, 2.5, 3.3, 5, 12 and 15 V.

The PO/HS series has an efficiency of 87% (typical). The most interesting features include output short circuit protection (hiccup, continuous & auto recovery), output overvoltage protection (clamp mode) and over-temperature protection. The input/output isolation is 1500 V DC (1.5 kV DC). The switching frequency is a constant 300 kHz (typical). The ambient operating temperature range is from -40°C to +85°C with derating.
