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.
