Fig 11. Typical application circuit using the PIP202-12M in a four-phase converter.
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
the design of the PIP202-12M between V_DDC and CB.
