PQ60025EKX20 Datasheet, PDF (1/15 Pages) SynQor Worldwide Headquarters – Eighth-brick DC-DC Converter

Technical
Specification
PQ60025EKx20
48V
Input
2.5V
Output
20A
Current
The PowerQor^® Eighth-brick converter series is composed
of next-generation, board-mountable, isolated, fixed
switching frequency dc-dc converters that use synchronous
rectification to achieve extremely high power conversion
efficiency. The power dissipated by the converter is so low
that a heatsink is not required, which saves cost, weight,
height, and application effort. All of the power and control
components are mounted to the multi-layer PCB substrate
with high-yield surface mount technology. Since the
PowerQor converter has no explicit thermal interfaces, it is
extremely reliable. RoHS Compliant (see page 15).

DC-DC Converter
Operational Features
• High efficiency, 86% at full load
• Delivers up to 20A of output current (50W) 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 means no preload resistors required

Module
Control Features
Mechanical Features
• Industry standard eighth-brick pin-out configuration
• Industry standard size: 0.90”x2.3” (22.9x58.4mm)
• Total height only 0.320” (8.13mm), permits better airflow and
smaller card pitch
• Total weight: 0.85oz. (24 grams)
• Flanged pins designed to permit surface mount soldering
(avoid wave solder) using FPiP technique
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 permanent damage and consequent
hazardous conditions
• Active back bias limit prevents damage to converter
from external load induced pre-bias
• Output over-voltage protection protects load from
damaging voltages
• Thermal shutdown protects converter from abnormal
environmental conditions
• On/Off control referenced to input side (positive and negative logic
options are available)
• Remote sense for the output voltage compensates for output
distribution drops
• Output voltage trim permits custom voltages and voltage margining
Safety Features
• 2000V, 30MΩ input-to-output isolation provides input/output
ground separation
• UL 60950-1 recognized (US & Canada),basic insulation rating
• TUV certified to EN60950-1
• Board and plastic components meet UL94V-0 flammability
requirements
