GENERAL SPECIFICATION
Efficiency: Typ.81%, various with input.
Switching Frequency: Fixed frequency 450K Hz.
Circuit Topology: 450K Hz. Forward Circuit.
Transient Response: Full to 1/2 load <200 uSec.
Case: Black coated aluminum with non-conductive
metal base.
Weight: 20.0g (0.71 Oz.).
Power Density: 12.0Watts./ Cubic inch.
Operating Temperature: -40°C to +85°C range. –25°C to
+71°C @ full load without derating. Derating linearly
3.5%/ °C from +71°C @ full load to +85°C @ half-load.
Storage Temperature: -55°C to +110°C.
Humidity: Up to 95% RH, Non-condensing.
Temperature Coefficient: 0.02% /°C.
Cooling: Convection cooling up to 60°C @F-L. At least
100LFM moving air is recommended for F-L >+60°C in
a confined area.
Commercial Grade: Full load up to +71°C with moving air.
Industrial Grade: +71 to +85°C F-L to H-L with moving air.
NOTE:(1) All measurements are at nominal input, full load and +25°C unless otherwise specified.
(2) Line Regulation measured from High to Low Lines at full load.
(3) Load Regulation measured from Full Load (F-L) to Half-Load (H-L) at nominal input.
(4) Correct fuse size by calculating the max. DC current drain at low Line input & Load and then adding 20-25% for the desired fuse size.
