NOTE ON USE (Continued)

●Instructions of pattern layouts

1. In order to stabilize VIN voltage level, we recommend that a by-pass capacitor (CIN) be connected as close as possible to the VIN (No.6) & VSS

(No.5) pins.

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

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

4. Make sure that the PCB GND traces are as thick as possible, as variations in ground potential caused by high ground currents at the time of

switching may result in instability of the IC.

5. This series’ internal driver transistors bring on heat because of the output current and ON resistance of driver transistors.

6. Please connect Lx (No.1) pin and L1 (No.7) pin by wiring on the PCB.

7. Please connect VOUT (No.3) pin and L2 (No.8) pin by wiring on the PCB.
