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.

Notes:
*
All parameters measured at Tc = 25°C, nominal input voltage
and full rated load unless otherwise noted. 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) Line regulation is for a 1.0% change in input voltage.
(2) Noise is measured per CALEX application notes. Measurement
bandwidth is 20 MHz. Output noise is measured with a 10µF/25V
(3)
(4)
(5)
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.
Specifications subject to change without notice.
Water Washability - Calex DC/DC converters are designed to
withstand most solder/wash processes. Careful attention should
be used when assessing the applicability in your specific
manufacturing process. Converters are not hermetically sealed.
