Typical Performance Of The Reference Desig
The reference design implemented 1.5mOhm output droop impedance as shown in Fig. 9.
The efficiency of the design is depends on the MOSFET being used and thermal management requirements of
controlling the PCB temperature and the MOSFET junction temperature. The following efficiency curve is corresponding
to 4mOhm bottom FET, while the top FET has 12 mOhm Rdson.
