6.5 APPLICATION SUGGESTIONS FOR HIGHER CURRENTS
For higher output currents, up to 20A, the following configuration can be used (with reference to the demo board
schematic):
Q1,Q2,Q3: STS11NF30L
Q4,Q5,Q6: STS17NF3LL
L: 2.5
H Magnetic 77121A7 Core 7T 2x AWG16
In these conditions, the following performance have been achieved:
Table 8.
For currents higher than 20A, bigger mosfets should be selected (e.g. STS25NH3LL) both for the high side and
low side (depending on the duty cycle and input voltage).

6A DEMO BOARD DESCRIPTION
A compact demo board has been realized to manage currents in the range of 5A-6A .
The external power mosfets are included in a single SO8 package to save space and increase power density.
Two separate rails are provided, for VCC and VIN. They can be connected together by shorting the jumper J1.
The PGOOD signal is used as a logic level and it's been pulled up to VIN because there's no other appropriate
voltage available on the demo board. In case of input voltage higher than 7V (PGOOD Pin Maximum Ab-
solute Rating) a 5V reference is required.
