The HPQ-12/25-D48 series offers high output
current (up to 25 Amps) in an industry standard
“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 specications 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
external remote On/Off control may use either posi-
tive or negative polarity. Remote Sense inputs com-
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 indenite
short-circuit protection. Additional safety features
include output overvoltage protection and reverse
conduction elimination. The synchronous rectier to-
pology offers high efciency for minimal heat buildup
and “no heat sink” operation. The HPQ-12/25-D48
series is certied 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.
