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 at-

tachment 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

chop the DC input voltage into a high frequency square

As an alternative to application and removal of the DC volt-

wave, apply this chopped voltage to the power transformer.

As this switching is initiated, a voltage is impressed on a

second winding of the power transformer which is then

rectified and applied to the primary bias supply. When this

occurs, the input voltage is excluded from the bias voltage

generator and the primary bias voltage becomes internally

generated.

age to the input, the user can control the converter output

by providing TTL compatible, positive logic signals to either

of two enable pins (pin 4 or 12). The distinction between

these two signal ports is that enable 1 (pin 4) is referenced

to the input return (pin 2) while enable 2 (pin 12) is refer-

enced to the output return (pin 8). Thus, the user has

access to an inhibit function on either side of the isolation

barrier. Each port is internally pulled “high” so that when not

used, an open connection on both enable pins permits nor-

mal converter operation. When their use is desired, a logi-

cal “low” on either port will shut the converter down.

The switched voltage impressed on the secondary output

transformer windings is rectified and filtered to provide the

positive and negative converter output voltages. An error

amplifier on the secondary side compares the positive out-

put voltage to a precision reference and generates an error

signal proportional to the difference. This error signal is

magnetically coupled through the feedback transformer into

the control section of the converter varying the pulse width

of the square wave signal driving the MOSFETs, narrowing

the pulse width if the output voltage is too high and widening

it if it is too low. These pulse width variations provide the

necessary corrections to regulate the magnitude of output

voltage within its’ specified limits.

Because the primary portion of the circuit is coupled to the

secondary side with magnetic elements, full isolation from
