*1. Refer to the data sheet of the S-8225A Series for the recommended value for external components
of the S-8225A Series.
*2. Use the products with the same model number for FET1 and FET2.
*3. Set up the optimal constant according to the FET in use.
Caution 1. The above constants may be changed without notice.
2. The example of connection shown above and the constants do not guarantee proper operation.
Perform thorough evaluation using the actual application to set the constant.
3. The DP pin should be open.
