Technical Specification
Eighth
Brick
48Vin 2.5Vout 20A
20 Amp, No Heatsink, Isolated DC/DC Converter
The PQ60025EGL20 PowerQor
™
Giga eighth-brick
converter is a next-generation, board-mountable,
isolated, fixed switching frequency DC/DC
converter that uses synchronous rectification to
achieve extremely high 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 tech-
nology. Since the PowerQor converter has no
explicit thermal connections, it is extremely reliable.
PQ60025EGL20 Module
Operational Features
• High efficiency, 87% at full rated load current
• Delivers up to 20 amps of output current with mini-
mal derating - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V
100ms input voltage transient protection
• Fixed frequency switching provides predictable EMI
performance
• No minimum load requirement means no preload
resistors required
Protection Features
• Input under-voltage lockout disables converter at
low input voltage conditions
• Output current limit and short circuit protection
protects converter from excessive load current or
short circuits
• Output over-voltage protection protects load from
damaging voltages
• Thermal shutdown protects converter from abnor-
mal environmental conditions
Mechanical Features
• Industry standard eighth-brick pin-out configuration
• Industry standard size: 0.90” x 2.3”
• Total height less than 0.335” (8.5mm), permits bet-
ter airflow and smaller card pitch
• Total weight: 19 grams (0.68 oz.), lower mass
greatly reduces vibration and shock problems
Safety Features
• 2000V, 10 MΩ input-to-output isolation provides
input/output ground separation
• UL 1950 recognized (US & Canada), basic insula-
tion rating
• TUV certified to EN60950
• Meets 72/23/EEC and 93/68/EEC directives
which facilitates CE Marking in user’s end product
• Board and plastic components meet UL94V-0 flam-
mability requirements
Control Features
• 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
