DC-DC Converter Packs 15 Watts Into 1 in.2

Two series were added to TDK-Lambda’s PX family of DC-DC converters. The fully-isolated PXA and PXB series have a tiny 1-in. x 1-in. footprint and are designed for applications ranging from communications to factory automation equipment. They are available in open frame (PXA) and shielded metal case (PXB) versions. The PXA Series offers single-output models with nominal inputs of 24 V and 48 VDC in 2:1 and wide 4:1 versions. The PXB Series offers both single- and dual-output models with nominal inputs of 12 VDC in a 2:1 version and inputs of 24 V and 48 VDC in 2:1 and wide 4:1 versions. Available single-output voltages for the PXA and PXB series include 3.3 V, 5 V, 12 V, and 15 VDC. In addition, the PXB series offers dual-output models that provide +/-5 V, +/-12 V, and +/-15 VDC outputs. Efficiency is up to 88%. Remote on/off and output adjustment features are standard, plus all models include overvoltage and over-current/short-circuit protection. Operating temperature range is -40°C to +85°C. The PXA is available in through-hole or SMD mounting formats, and the PXB comes in a through-hole mounting format. All models are CE-Marked and are certified to UL/CSA/EN60950-1 safety standards. They also meet the rigorous MIL-STD-810F thermal shock and vibration specifications. The PXA and PXB series are available now and are priced from $28.00 each in 500-unit quantities.
