Selection of Components Externally Connected

Follow the steps as shown below for selecting the external components.

1. Computation of Input Peak Current IL_MAX from application condition

2. Set the RCS value so that it becomes IOCP>IL_MAX

3. Select the value of L so that it becomes 0.05V/μs<

･

RCS<0.63xFosc [MHz]

Please judge the L value. If it’s OK, go to 4. And if it’s NG, go back to 1.

4. Select the coil, schottky diode, MOSFET and RCS which meets the current

and voltage ratings.

5. Select the output capacitor which meets with the ripple voltage requirements.

6. Select the input capacitor.

8. Phase Characteristics adjustment (CPC, RPC)

9. Over-Voltage Protection setting (ROVP1, ROVP2).

10. Soft Start Time Selection (CSS).

11. Check the Startup Time

VOUT

L

L value is

feed back

7. Select the BOOT – SW capacitor.

12. EN restart check

13. Actual Operation Confirmation

Cpc, CSS adjustment

(When use Boost

application)
