VKP100MT Series are Approved
to UL/CUL1950, EN 60950
The VKP100xT Series are members
of the VK high density DC/DC
converter family. They are multiple
output DC/DC converters offered in a
33-75 input voltage range. Their
versatile architecture featuring fully
isolated channels enables the system
designer to utilize the converter in
either a single, dual or triple output
scheme without excessive minimum
load requirements or cross regulation
degradation.
The VKP100xT's architecture
results in an economical and practical
solution for use in distributed power
schemes for today's demanding
telecommunication and electronic
data processing applications requiring
ground separation between noise
sensitive digital logic and bipolar
analog components. The VKP100xT's
proprietary control circuity responds
to 50-100% load steps in 35µSeconds
to within 1% of nominal Vout. The
peak deviation will not exceed 10%
of Vout for pulsed load slew rates in
excess of 75 Amps per microsecond.
The VKP100xT is ideal for electronic
data processing applications utilizing
modern disk drives and low voltage
microprocessors that require dynamic
load current response while maintain-
ing tight output voltage tolerances.
