DC/DC Conver ter
The PQ60010EML15 PowerQor
™
Mega eighth-brick con -
b
verter is a next-generation, board-mountable, isolated, fixed
g
m
switching frequency DC/DC converter that uses synchro -
nous rectification to achieve extremely high conversion effi -
ciency. 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 com -
ponents are mounted to the multi-llayer PCB substrate with
high-yield surface mount technology. Since the PowerQor
y
converter has no explicit thermal interfaces, it is extremely
reliable.
Operational Features
• High efficiency, up to 82% at 1.0Vout
• Delivers up to 15 amps of output current 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
PQ60010EML15 Module
Pr otection 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 conse-
quent hazardous conditions
• Active back bias limit prevents damage to converter
from external load induced pre-bias
• Output over-voltage protection protects load from dam-
aging voltages
• Thermal shutdown protects converter from abnormal
environmental conditions
Mechanical Features
• Industry standard eighth-brick pin-out configuration
• Industry standard size: 0.90” x 2.3” (22.9x58.4mm)
• Total height only 0.335” (8.5mm), permits better airflow
and smaller card pitch
• Total weight: 0.68 oz. (19 grams)
• Flanged pins designed to permit surface mount solder-
ing (avoid wave solder) using FPiP technique
Safety Features
• 2000V, 30 MΩ input-to-output isolation provides
input/output ground separation
• UL 1950 recognized (US & Canada), basic insulation
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 flammabil-
ity requirements
Contr ol 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

0.080” (2.03mm) diameter standoff shoulders.
2) Pins 4 and 8 are 0.062” (1.57 mm) diameter with
0.100” (2.54 mm) diameter standoff shoulders.
3) Other pin extension lengths available. Recommended pin
length is 0.03” (0.76mm) greater than the PCB thickness.
4) All Pins: Material - Copper Alloy
Finish - Tin/Lead over Nickel plate
5) Undimensioned components are shown for visual
reference only.
6) All dimensions in inches (mm)
Tolerances: x.xx +/-0.02 in. (x.x +/-0.5mm)
x.xxx +/-0.010 in. (x.xx +/-0.25mm)
7) Weight: 0.68 oz. (19 g) typical
8) Workmanship: Meets or exceeds IPC-A-610C Class II
9)
UL/TUV standards require a clearance greater than 0.04”
(1.02mm) between input and output for Basic insulation. This
issue should be considered if any copper traces are on the top
side of the user’s board. Note that the ferrite cores are consid-
ered part of the input/primary circuit.
