See "Standard Operation" on page 57 for a brief explanation of Constant Voltage
and Constant Current Mode operation.
•
See "Using Over Voltage Protection (OVP)" on page 61 to "Over Temperature
Protection (OTP)" on page 70 for more about power supply functions such as
OVP, shutdown function, OTP, and using multiple supplies.
