Name and Function
Power Ground pin
Switching node connection to the internal PFET switch and NFET synchronous rectifier.
Feedback analog input for the DC-DC converter. Connect to the output filter capacitor.
Power supply input for switcher. Connect to the input filter capacitor.
Enable input for the linear regulator. The linear regulator is in shutdown mode if voltage at this pin is
< 0.4V and enabled if > 1.1V. Do not leave this pin floating.
Enable input for the DC-DC converter. The DC-DC converter is in shutdown mode if voltage at this pin is <
0.4V and enabled if > 1.1V. Do not leave this pin floating.
Input power to LDO. ( Must tie to V BATT at all times )
Enable input for the linear regulator. The linear regulator is in shutdown mode if voltage at this pin is
< 0.4V and enabled if > 1.1V. Do not leave this pin floating.
Quiet GND pin for LDO and reference circuit.
Voltage output of the linear regulator.
Voltage output of the low input linear regulator
Input power to LILO (V IN_LILO connects to output of DCDC or standalone).
