HIGH DENSITY DC/DC CONVERTER
VKA100xS Series
FEATURES
DESCRIPTION
G 18 - 36V & 33 - 75V INPUT RANGE
The VKA100xS Series DC/DC converters present an
economical 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

The VKA100xS's proprietary control circuitry responds
to 50-100% load steps in 100µSeconds to within 1%
nominal 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.

MATERIAL: Units are encapsulated in a low thermal
resistance molding compound which has excellent
chemical resistance and electrical properties in high
humidity environments and over a wide operating
temperature range. The encapsulant and outer shell of
the unit have UL94V-0 ratings. Lead material is solder
plated to allow ease of solderability.

OUTPUT VOLTAGE ADJUST
OVP NOTE
This feature allows the user to accurately adjust the
module's output voltage set point to a specified level.
This is achieved by connecting a resistor or potentiometer
from the TRIM terminal to either the +Vout terminal (for
increased Vout) or the -Vout terminal (for decreased
Vout). The formulae below describe the trim resistor
value to obtain a Vout change of ∆%. VO is output
voltage prior to adjustment (3.3V, 5V, 12V, 15V, 24V or
28V).
Special attention should be given to the peak voltage
deviation during a dynamic load step when trimming the
output above the original set point to avoid tripping the
overvoltage protection circuit. Should an OVP condition
occur, the converter will go into a latch condition and
must be externally reset before it will return to normal
operation.
