HPD15 SERIES

Single, dual and triple output

[ 2 YEAR WARRANTY ]

• 2.0 x 2.0 x 0.4 inch package (singles and duals)

• 2:1 wide input voltage range

• 30 models available including 2.1V and 3.3V outputs

• Indefinite short circuit protection

• EN55022 conducted emissions level A

• Designed to meet EN60950 and IEC950

The HPD15 series of DC/DC converters offer 15 Watts of output power in a high

density 2 x 2 inch case. A range comprises 30 models with 2:1 wide input

voltages of 9-18V, 18-36V and 36-72VDC. Single, dual and triple outputs are

available with 2.1V and 3.3V single outputs suitable for low voltage logic

requirements. Standard features of the HPD15 series include indefinite short

circuit protection and undervoltage lockout. The series meets EN55022 level A

conducted and radiated emissions. In addition to this, all outputs are regulated

and isolated from the input. Typical applications are on board logic or analog

circuits supplied by telecom distribution power voltages, cellular and

telecommunications systems.
