Function
Low power controller ground. Can be left unconnected for load currents below 600 mA.
Shuts down the IC completely and decreases current consumed by the IC to < 1 μA.

Input node for buck mode and output node for boost mode.
Externally controlled synchronization signal. Logic high to low transition forces the clock synchronization. If not
used, the pin must be connected to V DD , or logic high.
Low power controller ground
1.3 V reference. Decoupled with 0.1 μF capacitor.
Output voltage feedback connected to the inverting input of an error amplifier.
Error amplifier output for external compensation network.
External resistor to determine the switching frequency.
Input supply voltage for the analog circuitry. Input voltage range is 2.7 V to 6 V.
Direct output voltage sensing to control peak inductor current in PSM mode.
Supply voltage for the internal MOSFET drive circuit.
Power ground.
Determines the converter topology. Connect to AGND for buck or V DD for boost.
Inductor connection node
