60 WATT SINGLE OUTPUT

HIGH DENSITY DC/DC CONVERTER

VKA60xS Series.

DESCRIPTION

FEATURES

! 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

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.

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.
