automotive start-stop application to maintain a 12V @ 30A rail
over a 6-11V input range. ISL6609A inverting MOSFET drivers

FIGURE 23. CONFIGURATIONS FOR 12-PHASE OPERATION
Figure 23 shows the step-by-step setup as follows:
1. Connect the CLK_OUT pin of the master IC to the SYNC pin of
the slave IC.
2. Set the master IC’s switching frequency as desired frequency,
set the slave IC’s switching frequency 20% below the master
IC’s.
3. Connect both IC’s COMP, SS and FB pins together.
4. Both IC’s DRIVE_EN pin should be AND together to provide
system’s driver enable signal.
5. Since PGOOD, VOUT_OVB and VIN_OVB pins are open drain
structure, both IC’s PGOOD, VOUT_OVB and VIN_OVB pins can
be tied together and use one pull - up resistor to connect to
VCC.
6. If phase dropping function is needed, tie both IC’s IOUT and
MODE pins together.
