Product Data Sheet
60 WATT SINGLE OUTPUT
HIGH DENSITY DC/DC CONVERTER
VKA60xS Series
DESCRIPTION
FEATURES
G 18 - 36V & 33 - 75V INPUT RANGE
The VKA60xS Series DC/DC converters present an eco-
nomical and practical solution for distributed power
system architectures which require high power density
G SMALL SIZE: 2.28" X 2.4" X 0.50"
G HIGH EFFICIENCY: 87% TYPICAL AT 5V
and efficiency while maintaining system modularity and
upgradeability. With the ability to operate over a wide
input voltage range of 18 to 36 and 33 to 75 volts, these
modules are ideal for use in battery backup applications
common in todays' telecommunication and electronic
data processing applications. The output is fully isolated
from the input, allowing for a variety of polarity and
grounding configurations.
G 100µS TRANSIENT RESPONSE 50-100% LOAD STEP
G 420kHZ FIXED-FREQUENCY OPERATION
G OPERATION TO +100°C BASEPLATE TEMP.
G PRIMARY REMOTE ON/OFF, CHOICE OF POS/NEG
LOGIC
G ADJUSTABLE OUTPUT VOLTAGE
G REMOTE SENSE
The VKA60xS's proprietary control circuitry responds to
50-100% load steps in 100µSeconds to within 1% nomi-
nal Vout.
G CONTINUOUS SHORT-CIRCUIT PROTECTION
G THERMAL SHUTDOWN
The patented fixed frequency architecture combined with
surface mount technology results in a compact, efficient
and reliable solution to DC/DC conversion requirements.
G SAFETY PER UL1950, EN 60950 AND CSA 22.2 #234
G CASE GROUND PIN
