DESCRIPTION
3
V
Power ground; connected to the source of internal N-Channel power MOSFET
Signal ground; ground reference for all the control circuitry; needs to have only a single connection to PGND
Timing resistor to adjust the oscillation frequency of the converter
Chip enable; connects to logic HI (>1.6V) for chip to function
Low battery input; connects to a sensing voltage, or left open if function is not used
Low battery detection output; connected to the open drain of a MOSFET; able to sink 1mA current
Soft-start; connects to a capacitor to control the start-up of the converter
Voltage feedback input; needs to connect to resistor divider to decide V
Control circuit positive supply
Inductor drive pin; connected to the drain of internal N-Channel power MOSFET
