DC/DC Converter Requires No Heatsink

Boasting of very high efficiency of 86% at 40A, the PQ48025HNA40 dc/dc converter is a board-mountable, isolated, fixed-switching frequency device that uses synchronous rectification to achieve high conversion efficiency. The power dissipated by the converter is said to be low enough that no heat sink is required. All of the power and control components are mounted to the multi-layer pc board substrate with high-yield, SMT technology. Other key features include industry-standard pin-out configuration and size; a height of just 0.40" and weight of only 1.9 oz., a wide input voltage range; on/off control referenced to input side; remote sense for the output voltage; input under-voltage lockout and over-voltage shutdown; and thermal shutdown.
