BLOCK’S DIAGRAM DESCRIPTION

3.1 High/Low Side driving section

An High and Low Side driving Section provide the proper driving to the external Power MOS or IGBT. An high

sink/source driving current (450/250 mA typ) ensure fast switching times also when size4 Power MOS are used.

The internal logic ensures a minimum dead time to avoid cross-conduction of the power devices.

3.2 Timing and Oscillator Section

The device is provided of a soft start function. It consists in a period of time, TSS, in which the switching frequen-

cy shifts from fstart to fmin. This feature is explained in the following description (ref. fig.7 and fig.8).
