ISL78225
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 ANDed together to provide
the 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.

ISL78225EVAL1Z Evaluation
Board
The ISL78225EVAL1Z evaluation board is designed for
automotive trunk audio application to deliver 36V @ 10A over a
10-16V input range. ISL78420 100V inverting MOSFET drivers
with tri-state input capability facilitate synchronous boost
rectification and phase-dropping for high efficiency over the
entire load range. See AN1727 on the Intersil website,
www.intersil.com , for more information on ISL78225EVAL1Z.
