Application Examples

When using as Boost DC/DC converter

Figure 21. Boost application circuit

Note: When using as boost DC/DC converter, if the VOUT and LED terminal are shorted, the over-current from VIN cannot be

prevented. To prevent overcurrent, carry out measure such as inserting fuse in between VCC and RCS.

When using as Buck DC/DC Converter
