VKP60xT Series Approved to
UL/CUL 1950, EN60950
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 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 microsec-
ond. 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.
