The VKP60LTC and VKP60MTC Series are
members of the VK high density DC/DC converter
family. They are multiple output DC/DC convert-
ers offered in both a 18-40 and 33-75 input
voltage range. Their versatile architecture featur-
ing 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 VKP60xTC’s architecture results in an
economical and practical solution for use in dis-
tributed power schemes for today’s demanding
telecommunication and electronic data process-
ing applications requiring ground separation
between noise sensitive digital logic and bipolar
analog components. The VKP60xTC’s proprietary
control circuity responds to 50-100% load steps
in 35μSeconds to within 1% of nominal Vout.
The peak deviation will not exceed 7% of Vout
for pulsed load slew rates in excess of 75 Amps
per microsecond. The VKP60xTC is ideal for
electronic data processing applications utilizing
modern disk drives and low voltage micro-
processors that require dynamic load current
response while maintaining tight output voltage
tolerances.
