Description

Murata Power Solutions  has extended its HPQ range of high power quarter-brick isolated  DC-DC converters with the introduction of the HPQ-12/25-D48, a 300W  model with 12V output. The new model features a wide 2:1 input range  of 36 to 75V and output of 12V, plus high output current of up to  25A in an industry standard quarter-brick package (2.3” x 1.45” x  0.44”).

The HPQ-12/25-D48 also boasts high efficiency of up to  94.5%.
 

The HPQ-12/25-D48 is  ideal for a wide range of markets and applications, ranging from  industrial and instrumentation to computers and office equipment.  Excellent ripple and noise specifications assure compatibility with  circuits using CPUs, ASICs, programmable logic and FPGAs. Ideal for  battery-powered and telecom equipment, applications for the  HPQ-12/25-D48 include small instruments, area-limited  microcontrollers, data communications equipment, remote sensor  systems, vehicle and portable  electronics.
 

For systems requiring  controlled startup/shutdown, remote On/Off control is available with  negative or positive polarity. Users can also trim the output  voltage of the HPQ-12/25-D48 up or down by ±10% with an external  trim resistor. It also offers input-output isolation with Basic  insulation up to 2250Vdc. In addition, with a low profile open frame  package, the HPQ-12/25-D48 operates within the industrial  temperature range of -40°C to 85°C.
 

The power supply is  designed to meet UL/EN/IEC 60950-1 2nd edition safety approvals and  is RoHS-6 compliant. Optional features include: a base-plate, which  boosts the HPQ-12/25-D48's impressive thermal performance; conformal  coating; trim and sense functionality; and various pin  lengths.
