PIN FUNCTION
Control circuit negative supply
Oscillator timing capacitor; F OSC can be approximated by: F OSC (kHz) = 0.1843/C OSC , C OSC in μF
Control circuit positive supply
Ground return of the regulator; connected to the source of the low-side synchronous NMOS power FET
Ground return of the regulator; connected to the source of the low-side synchronous NMOS power FET
Power supply input of the regulator; connected to the drain of the high-side NMOS power FET
Power supply input of the regulator; connected to the drain of the high-side NMOS power FET
Chip enable, active high; a 2μA internal pull-up current enables the device if the pin is left open
Ground return of the regulator
Positive supply of the high-side driver
Inductor drive pin; high current digital output whose average voltage equals the regulator output voltage
Inductor drive pin; high current digital output whose average voltage equals the regulator output voltage
Positive supply of the low-side driver and input voltage for the high-side boot strap
Voltage feedback input; connected to an external resistor divider between V OUT and GND; a 125nA pull-up current
forces V OUT to V S in the event that FB is floating
Bandgap reference bypass capacitor; typically 0.1μF to GND
Ground return of the regulator
