“quarter brick” package requiring no heat sink for
most applications. The HPQ-12/25-D48 series de-
livers ?xed 12 Vdc output at 300 Watts for printed
circuit board mounting. Wide range inputs on the
2.3 ” x 1.45 ” x 0.49 ” converter are 36 to 75 Volts
DC (48 Volts nominal), ideal for datacom and telecom
systems. The ?xed output voltage is regulated to
within ±0.25%.
Advanced automated surface mount assembly
and planar magnetics deliver galvanic isolation
rated at 2250 Vdc for basic insulation. To power
digital systems, the outputs offer fast settling to
current steps and tolerance of higher capacitive
loads. Excellent ripple and noise speci?cations as-
sure compatibility to CPU’s, ASIC’s, programmable
logic and FPGA’s. No minimum load is required. For
systems needing controlled startup/shutdown, an

? Disk farms, data centers and cellular repeater sites
? Remote sensor systems, dedicated controllers
pensate 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. Overcurrent protection using the
“hiccup” autorestart technique provides inde?nite
short-circuit protection. Additional safety features
include output overvoltage protection and reverse
conduction elimination. The synchronous recti?er to-
pology offers high ef?ciency for minimal heat buildup
and “no heat sink” operation. The HPQ-12/25-D48
series is certi?ed to full safety standards UL/EN/IEC/
CSA 60950-1, 2nd edition and RFI/EMI conducted/
radiated emission compliance to EN55022, CISPR22
with external ?lter.
