Unique among quarter-brick DC-DC converters,
the HPQ-3.3/50-D48 series offers very high output
current (up to 50 Amps) in an industry standard
“quarter brick” package requiring no heat sink. The
HPQ-3.3/50-D48 series delivers up to 165 Watts
?xed voltage output for printed circuit board mount-
ing. Wide range inputs on the 2.3 " x 1.45 " x 0.40 "
converter are 36 to 75 Volts DC (48 Volts nominal),
ideal for datacom and telecom systems. The ?xed
output voltage is regulated to within ±1% and may
be trimmed within ±10% of nominal output.
Advanced automated surface mount assembly
and planar magnetics deliver full magnetic and
optical isolation with Basic protection up to 2250
Volts. To power digital systems, the outputs offer
fast settling to current steps and tolerance of
higher capacitive loads. Excellent ripple and noise
speci?cations assure compatibility to CPU’s, ASIC’s,
programmable logic and FPGA’s. No minimum load
is required. For systems needing controlled startup/

shutdown, an external remote On/Off c control may
use either positive or negative polarity. Remote
Sense inputs compensate for resistive line drops at
high currents.
A wealth of self-protection features avoid prob-
lems with both the converter and external circuits.
These include input undervoltage lockout and
overtemperature shutdown using an on-board tem-
perature sensor. Excessive overcurrents limit their
power using the “hiccup” autorestart technique
and the outputs may be short-circuited inde?nitely.
Additional safety features include output overvolt-
age protection and reverse conduction elimination.
The synchronous recti?er topology offers high
ef?ciency for minimal heat buildup and “no heat
sink” operation. The HPQ-3.3/50-D48 series meets
safety certi?cations to UL/EN/IEC/CSA 60950-1,
2nd Edition and RFI/EMI conducted/radiated
emission compliance to EN55022-CISPR22 with
external ?lter.
