Although incorporating several sophisticated and useful

ancilliary features, basic operation of the AFL120XXDseries

can be initiated by simply applying an input voltage to pins 1

and 2 and connecting the appropriate loads between pins 7,

8, and 9. Of course, operation of any converter with high

power density should not be attempted before secure

attachment to an appropriate heat dissipator. (See Thermal

Considerations, page 7)

Circuit Operation and Application Information

The AFL series of converters employ a forward switched

mode converter topology. (refer to Figure I.) Operation of

the device is initiated when a DC voltage whose magnitude

is within the specified input limits is applied between pins 1

and 2. If pins 4 and 12 are enabled (at a logical 1 or open)

the primary bias supply will begin generating a regulated

housekeeping voltage bringing the circuitry on the primary

side of the converter to life. Two power MOSFETs used to Inhibiting Converter Output (Enable)
