Typical Applications (Continued)
A minimum value for an ideal output capacitor C3, could be
calculated asC=I
o xt/
∆V where I
o is the load current, t is
the transistor on time (typically 0.4/f
osc), and
∆V is the peak-
to-peak output voltage ripple. A larger output capacitor than
this theoretical value should be used since electrolytics have
poor high frequency performance. Experience has shown
that a value from 5 to 10 times the calculated value should
be used.
For good efficiency, the diodes must have a low forward
voltage drop and be fast switching. 1N5819 Schottky diodes
work well.
Transformer selection should be picked for an output tran-
sistor “on” time of 0.4/f
osc, and a primary inductance high
enough to prevent the output transistor switch from ramping
higher than the transistor’s rating of 750 mA. Pulse Engi-
neering (San Diego, Calif.) and Renco Electronics, Inc.
(Deer Park, N.Y.) can provide further assistance in selecting
the proper transformer for a specific application need. The
transformer used in Figure 23 was a Pulse Engineering
PE-64287.
