Linear topology for high output accuracy and regulation

[ 2 YEAR WARRANTY ]

The PM900 Series of 5 and 6 Watt DC/DC converters are a broad line of high

performance modules with many important features and specifications as

standard. All models contain Pi-type input filters to minimise reflected ripple

current. They are packaged in low profile 2.0 x 2.0 x 0.4 inch cases with

standard and two alternate pin-outs designed for direct PC card mounting. The

units also feature output current limiting, short-circuit protection and

input/output isolation of 500VDC. Other specifications include: an efficiency of

65%; line regulation of ±0.02%; load regulation of ±0.04% for single output

models and ±0.05% for dual output models; low ripple and noise (10mV pk-pk

for single output models and 6mV pk-pk for dual output models); and an output

voltage accuracy of ±1.0%. PM900 Series DC/DC converters are intended for a

wide variety of general industrial applications, especially where low noise

performance is required.

Notes

Figures are peak-to-peak.

Alternate pin-out versions, if available, are designated by the suffixes

shown. For example, model PM901 is available in two alternate pin-out

versions, i.e. PM901A and PM901B. See case drawings below.

Fixed frequency design provides for easier input filtering and better noise

performance.

Short circuit protection is achieved using a thermal limit at 130°C max. An

extended short circuit of >8 hours will affect the units reliability.
