NOTES:
1. In order to get good performance, itâs important to select the right CPUMP, CPVSS and CBYP in application. All tests are performed
with circuit set up with X5R and X7R capacitors. Capacitors having high dissipative loss, such as Y5V capacitor, may cause
performance degradation and unexpected system behavior.
2. A 10kΩ resistor is recommended to be put between EN pin and external power supply or control I/O.
