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.
