3 Watt UM Single Series DC/DC Converters Features ! 3 Watts Semi-Regulated Outputs ! High Efficiency ! Industry Standard 24 Pin DIP Package ! Water Washable Construction ! 5 Year Warranty ! Customs and Specials Available Selection Chart INPUT RANGE VDC MODEL Description The CALEX UM series provides a semi-regulated output in a small package with an industry standard pinout. Isolation allows flexibility in connecting grounds for lowest system noise. The high efficiency means efficient use of your system power. The UM series contains filters at the input and output and generally no extra parts are required. Four terminal operation allows using negative inputs and/or connections to provide a negative output.

Refer to the CALEX Application Notes for the definition of terms, measurement circuits and other information. All tests with connections to all active pins. Operation with connection to only one pin will not harm the unit. (1) (2) (3) (4) Line regulation is for a 1.0% change in input voltage. Noise is measured per CALEX application notes. Measurement bandwidth is 20 MHz. Output noise is measured with a 10µF/25V solid tantalum capacitor connected across the output pins. The case thermal impedance is specified as the case temperature rise over ambient per package watt dissipated.
