55 Watt K Triple Series DC/DC Converters

Description

Features

ꢀ

The 55 Watt Triple Series consists of separate power sections

for the single and dual outputs. These power sections are

operated in anti-phase to each other to reduce the ripple

current stress on the input components and the reflected input

ripple. The main benefit of two separate power sections is the

excellent regulation achieved by all outputs. An order of

magnitude regulation improvement is obtained over

competitive designs. There is no cross regulation between +5

output and the dual outputs. This means that the dual output

voltages are independent of the +5 Volt loading and visa

versa.

Very Low Noise, < 50 mV P-P Maximum

ꢀ

No derating to 80°C Case Temperature

Excellent noise performance is attained by using a 0.040

inch thick aluminum case, pot core and toroidal magnetics,

double shielded transformers and both normal mode and

common mode input filtering.

ꢀ

Five Year Warranty

The input and outputs are protected from overvoltage by

transientvoltagesuppressordiodes. Theoutputsareprotected

from faults with pulse by pulse digital current limiting.
