HPQ-12/25-D48 Series  
Isolated 300-Watt Quarter Brick DC/DC Converters  
s
PRODUCT OVERVIEW  
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 fixed 12 Vdc output at 300 Watts for printed  
circuit board mounting. Wide range inputs on the  
2.3” x 1.45” x 0.44” converter are 36 to 75 Volts  
DC (48 Volts nominal), ideal for datacom and telecom  
systems. The fixed output voltage is regulated to  
within 2ꢀ.  
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 specifications 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 indefinite  
short-circuit protection. Additional safety features  
include output overvoltage protection and reverse  
conduction elimination. The synchronous rectifier to-  
pology offers high efficiency for minimal heat buildup  
and “no heat sink” operation. The HPQ-12/25-D48  
series meets full safety standards to UL/EN/IEC/CSA  
60950-1, 2nd edition and RFI/EMI conducted/radi-  
ated emission compliance to EN55022, CISPR22 with  
external filter.
