11. Application information

11.1 Typical application

A typical four-phase buck converter is shown in Figure 11. This system uses four

PIP202-12M devices to deliver a continuous output current of 80 A at an operating

frequency of 500 kHz.

Remark: An external bootstrap diode is not required as one is already integrated into

Fig 11. Typical application circuit using the PIP202-12M in a four-phase converter.
