DC/DC Converter
The PQ60120QEA25 PowerQor^® Exa quarter-brick
converter is a next-generation, board-mountable, isolated,
fixed switching frequency DC/DC converter. The Exa series
offers industry leading power density for standard isolated
DC/DC converters with both a wide input range and a
tightly regulated output. Targeted for use in intermediate bus
architectures, this module supplies an isolated step down
voltage from 35-75V to 12V and provides more available
power and higher efficiency than most competitive bus
converters. This converter is available in open-frame and
baseplated versions. RoHS Compliant (see page 13).
Operational Features
• Ultra-high efficiency, >96% at full rated load current,
>96.5% at half rated load current
• Delivers up to 25A of output current (300W) with minimal
derating - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V 100ms
input voltage transient capability
• Fixed frequency switching provides predictable
EMI performance
• No minimum load requirement - no preload resistors required
• Wide output voltage trim range (-50% to +5%)
Mechanical Features
• Industry standard quarter-brick pin-out configuration
• Industry standard size: 1.45” x 2.3” (36.8x58.4mm)
• Total height less than 0.436” (11.06mm), permits better
airflow and smaller card pitch
• Total weight: 1.5 oz. (42 grams)
• Open frame units have flanged pins designed to permit
surface mount soldering (avoid wave solder) using
FPiP technique
PQ60120QEA25 Module
Protection Features
• Input under-voltage lockout disables converter at low
input voltage conditions
• Output current limit and short circuit protection protects
converter and load from damage and consequent hazardous
conditions
• Active back bias limit provides smooth startup with
external load induced pre-bias
• Latching output over-voltage protection protects load
from damaging voltages
• Thermal shutdown protects converter from abnormal
environmental conditions
Control Features
• On/Off control referenced to input side (positive and
negative logic options are available)
Safety Features
• 2250V input-to-output isolation
• UL 60950-1:2003, basic insulation
• CAN/CSA-C22.2 No. 60950-1:2003
• EN60950-1:2001
• RoHS compliant (see page 13)
