DC/DC Conver ter
ter
 Ultra-high efficiency, 89% at half load, 85% at full load
 Delivers up to 40 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 per-
formance
 No minimum load requirement means no preload resis-
tors required
Operational 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

otection Features
 2000V, 30 M
 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
Safety Features
 Industry standard quarter-brick pin-out configuration
 Industry standard size: 1.45” x 2.3” (36.8x58.4mm)
 Total height less than 0.43” (10.9mm), permits better
airflow and smaller card pitch
 Total weight: 1.5 oz. (42 grams)
 Flanged pins designed to permit surface mount solder-
ing (avoid wave solder) using FPiP technique
Mechanical 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
