13 - APPLICATION DIAGRAM
The diodes for the recirculation current directly im-
pact the device performances. High Voltage di-
odes with recovery time inferior to 50ns are recom-
mended. Shorter recovery times will improve the
power efficiency of the application.
The rise and fall time of the output signal is adjust-
ed by the value of the inductance for a given ca-
pacitive load.
trise (tfall) is calculated by the following formula :
A 1nF bootstrap capacitor is recommended.
The bootstrap capacitor allows the output signal to
reach the
Vpp
value. For a given output level, the
power efficiency will be increased.
A 47
μ
F capacitor is recommended. The ripple on
the tank capacitor is reduced by increasing the
tank capacitor value.
Decoupling capacitors on the power supplies will
minimise the overshoots.
