Description
Input voltage power pin.
Inductor charging current passes through this pin.
Internal supply voltage.
Control circuitry powered from this pin.
Open drain battery low output.
V IN below battery low threshold pulls this node to ground. V IN above threshold, this node
is open.
Inductor current limit programming pin.
Tie pin to V IN for 0.95A peak inductor current limit. Tie pin to ground for 0.5A peak
inductor current limit. TTL input threshold.
Shutdown control input.
Tie to V IN for normal operation, tie to ground for shutdown. TTL input threshold.
External feedback network input connection.
Connect a resistor from FB to ground and FB to V OUT to control the output voltage
externally. This pin regulates to the internal bandgap reference voltage of 1.25V. Tie FB
to ground to use the internal divider for a preset output voltage of 3.3V.
Output voltage sense pin.
Used for internal feedback divider and timing circuit.
Internal ground pin.
Control circuitry returns current to this pin.
Power ground pin.
Synchronous rectifier current returns through this pin.
Inductor switching node.
Inductor tied between this pin and the output capacitor to create regulated output
voltage.
