11. Application information
11.1 Typical application
A typical four-phase buck converter is shown in Figure 11. This system uses four
PIP201-12M devices to deliver a continuous output current of 50 A at an operating
frequency of 500 kHz.
The dissipation in each PIP201-12M can be read from Figure 6. At 500 KHz and
12.5 A output current, the dissipation in each PIP201-12M is 2.7 W. In a typical
computer motherboard application, the thermal resistance of each PIP201-12M from
junction to ambient is 20 K/W. Assuming a maximum ambient temperature of 55
°C,
the maximum junction temperature (Tj(max)) is given by:
