Description
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.
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.
The input and outputs are protected from overvoltage by
transient voltage suppressor diodes. The outputs are protected
from faults with pulse by pulse digital current limiting.
