Isolation DC/DC Converter
The DQ62412QKA02 DualQor^™ Kilo series is a dual out-
put converter that uses the industry standard quarter brick
package size. The very high efficiency is a result of
SynQor’s patented topology that uses synchronous rectifica-
tion and an innovative construction design to minimize heat
dissipation and allow extremely high power densities. The
power dissipated by the converter is so low that a heatsink
is not required, which saves cost, weight, height, and appli-
cation effort. All of the power and control components are
mounted to the multi-layer PCB substrate with high-yield sur-
face mount technology, resulting in a more reliable product.
The Kilo series offers ample power output in an economical
package.
Operational Features
• High efficiency, > 85% at full rated load current
• Delivers up to 20 Watts of output power with no derat-
ing - no heatsink required
• Wide input voltage range: 35V – 75V, with 100V
100ms input voltage transient capability
• Fixed frequency switching provides predictable EMI per-
formance
• No minimum load requirement means no preload resis-
tors required
Mechanical Features
• Industry standard pin-out configuration
• Industry standard size: 1.45” x 2.3” (36.8x58.4mm)
• Total height less than 0.422” (10.72mm), permits better
airflow and smaller card pitch
• Total weight: 1.5 oz. (43 g)
• Flanged pins designed to permit surface mount solder-
ing (avoid wave solder) using FPiP technique
Control Features
• On/Off control referenced to input side (positive and
negative logic options are available)
• Output voltage trim: +10%/-10%, permits custom volt-
ages and voltage margining

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 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
Safety Features
• 2000V, 30 MΩ input-to-output isolation provides
input/output ground separation
• UL/cUL 60950 recognized (US & Canada), basic insu-
lation 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
