high current, the SCP protection may be triggered at startup.
2. Preset the power supply output to expected value (4V-6V), and then turn it off.
3. Connect the positive and negative terminals of the power supply output to the VCH and GND pins,
respectively.
4. Connect the positive and negative terminals of a battery (2.5V to 5V) to the VBAT and GND pins,
respectively.
5. Push the S1 button for longer than 2.2s, the DC/DC will be turned on automatically; Push the S1

µ
F capacitor on TEOL pin to provide voltage
filtering for low battery detection.
