Function
Bias supply voltage after start-up and feedback to the output voltage error amplifier.
Enable pin. Logic high enables the IC. Logic low disables the IC and disconnects the
load from the input. Shutdown current is <1µA.
Battery input voltage. Supplies the IC at start-up.
Inductor connection. Ties to the drains of the P-channel synchronous rectifier and the
N-channel MOSFET switch.
Boost converter output voltage; connects to the P-channel synchronous MOSFET
source. Bypass with ceramic capacitor to GND.
Signal and power ground. Connect output capacitor return.
