NOTES

2. Output ripple voltage is specified when measured with Intel specified capacitance at the output of the converter.

3. Transient response is specified with Intel specified capacitors at the output of the converter.

4. If remote sense is not required or used, the Sense(+) and Sense(–) pins must be connected to Vo(+) and Vo(–) respectively.

5. 10μF ceramic X5R or X6S.
