TDK-Lambda has added two new series to its already successful PX family of dc-dc converters. The fully-isolated PXA and PXB series have a tiny 1 x 1 inch 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 and 48Vdc in 2:1 and wide 4:1 versions. The PXB series offers both single and dual-output models with nominal inputs of 12Vdc in a 2:1 version and inputs of 24 and 48Vdc in 2:1 and wide 4:1 versions.
Available single-output voltages for the PXA and PXB series include 3.3, 5, 12 and 15Vdc. In addition, the PXB series offers dual-output models that provide +/- 5, +/- 12 and +/- 15Vdc outputs. Efficiency is up to 88%. Remote on/off and output adjustment (trim – single output models) features are standard, plus all models include overvoltage and overcurrent/short circuit protection. Operating temperature range is -40 to +85°C.
The PXA is available in through-hole or SMD mounting formats and the PXB in a through-hole mounting format. All models are CE-Marked and are certified to UL/CSA/EN60950-1 safety standards as well as meeting the rigorous MIL-STD-810F thermal shock and vibration specifications.
The PXA and PXB series are available now and priced from $28.00 each in 500-unit quantities.
