Power module takes on telecom, PoE apps

A solution for this complex situation has been achieved by combining two Over-Current Protection (OCP) methods. In the case of a short-duration overload, the hiccup-mode OCP uses a tightly controlled cycle-by-cycle current limitation; and in the case of longer overload, the hiccup-mode OCP will trigger for conventional hiccup protection.

Protection is not limited to two hiccup modes, as the hiccup activation time is proportional to temperature and becomes shorter with an increase in temperature, thereby limiting the energy dissipated during this period. Following activation of the Over-Temperature Protection (OTP), the module checks the OTP threshold to prevent any restart that could damage the module.

Available in an industry-standard sixteenth-brick footprint , with dimensions of 33mm x 22.9mm and a low-profile height of 9.4mm, the device delivers up to 50W, and provides up to 92 per cent efficiency at 50 per cent load and 27V input, guaranteeing low power dissipation and reduced energy consumption.

With natural convection, the module delivers full performance up to 80°C; and under 3m/sec convection cooling, full power can be delivered up to 96°C. Offering an MTBF (Mean-Time-Before-Failure) of 4.9 million hours, the PKU5510E meets safety requirements according to IEC/EN/UL 60950-1 and offers input/output isolation of 2,250Vdc.
