The PQ60120EML04 PowerQor Mega eighth-brick con-
verter 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 compo-
nents are mounted to the multi-layer PCB substrate with high-
™
yield surface mount technology. Since the PowerQor con-
verter has no explicit thermal interfaces, it is extremely reli-
able. RoHS compliant (see page 12).
Operational Features
PQ60120EML04 Module
• High efficiency, 90% at full rated load current
• Delivers up to 50 Watts of output power with minimal
derating - no heatsink required
Protection Features
• Wide input voltage range: 35V – 75V, with 100V
100ms input voltage transient capability
• Input under-voltage lockout disables converter at low
input voltage conditions
• Output current limit and short circuit protection pro-
tects converter and load from permanent damage and
consequent hazardous conditions
• Fixed frequency switching provides predictable EMI
performance
• No minimum load requirement means no preload
resistors required
• Active back bias limit prevents damage to converter
from external load induced pre-bias
• Output over-voltage protection protects load from dam-
aging voltages
Mechanical Features
• Thermal shutdown protects converter from abnormal
• Industry standard eighth-brick pin-out configuration
• Industry standard size: 0.90” x 2.3” (22.9x58.4mm)
environmental conditions
• Total height only 0.335” (8.5mm), permits better air-
flow and smaller card pitch
• Total weight: 0.68 oz. (19 grams)
Safety Features
• 2000V, 30 MΩ input-to-output isolation provides
• Flanged pins designed to permit surface mount solder-
input/output ground separation
ing (to avoid wave solder) using FPiP technique
• UL/cUL 60950-1 recognized (US & Canada), basic
insulation rating
Control Features
• TUV certified to EN60950-1
• On/Off control referenced to input side (positive and
negative logic options are available)
• Meets 72/23/EEC and 93/68/EEC directives which
facilitates CE Marking in user’s end product
• Remote sense for the output voltage compensates for
• Board and plastic components meet UL94V-0 flamma-
bility requirements
output distribution drops
• Output voltage trim permits custom voltages and volt-
age margining
