Instructions for pattern layouts

1. In order to stabilize VIN voltage level, we recommend that a by-pass capacitor CIN is connected as close as possible to the

VIN and VSS pins.

2. Please mount each external component as close to the IC as possible.

3. Place external components as close to the IC as possible and use thick and short traces to reduce the circuit impedance.

4. Make sure that the PCB GND traces are thick and wide as possible. Ground voltage level fluctuation created by high

ground current at the time of switching may cause instability of the IC.

5. The internal driver transistors bring on heat because of the IIN current and ON resistance of the driver transistors.
