DESCRIPTION
The VKP60LT and VKP60MT Series are members of the VK
high density DC/DC converter family. They are multiple
output DC/DC converters offered in both a 18-40 and 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 VKP60xT'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 VKP60xT's proprietary control circuity

VKP60MT SERIES ARE APPROVED TO UL/CUL1950, EN 60950
responds to 50-100% load steps in 35
Seconds 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 VKP60xT is ideal for electronic data
processing applications utilizing modern disk drives and
low voltage microprocessors that require dynamic load
current response while maintaining tight output voltage
tolerances.
