■NOTES ON USE (Continued)
●Notes on Layout
1. Position external components close to the IC so that the wiring is thick and short.
2. To minimize input voltage fluctuations, place C
3. Make the GND wiring sufficiently strong. Fluctuations of AGND or PGND voltage due to GND current during switching may cause unstable IC operation.
4. When creating a layout, refer to the circuit diagram and recommended layout pattern below.
5. This product is incorporated into a driver, and thus the driver transistor current and on-resistance may cause heat generation.
