The fully isolated, 15W PXA open-frame and PXB shielded-metal-case dc/dc converters provide 88% efficiency and have a —40 to +85°C operating temperature. The PXA series has single-output models with 24V nominal inputs and 48V dc in 2-to-1 and wide 4-to-1 versions. The PXB series comes in single- and dual-output models with 12V-dc nominal inputs in a 2-to-1 version and 24 and 48V-dc inputs in 2-to-1 and wide 4-to-1 versions. Single-output voltages include 3.3, 5, 12, and 15V dc, and the PXB series offers dual-output models providing ±5, ±12, ±15V-dc outputs. Standard models include remote on/off and output adjustment, including trim, single-output models, and devices with overvoltage and overcurrent/short-circuit protection are also available. Measuring 1×1-in. each, devices in the PXA and PXB series cost $28 (500).
