High efficiency, 90% at full rated load current
Delivers up to 40 Watts of output power 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 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. (43 g)
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)
Output voltage trim: +10%/-10%, permits custom volt-
ages and voltage margining
