Pin Descriptions
Pin Number
Pin Name
Pin Function
1
SGND
Control circuit negative supply.
2
COSC
Oscillator timing capacitor. FOSC can be approximated by: FOSC (kHz) = 0.1843/COSC, COSC in F.
3
VDD
Control circuit positive supply.
4
PGND
Ground return of the regulator. Connected to the source of the low-side synchronous NMOS power FET.
5
PGND
Ground return of the regulator. Connected to the source of the low-side synchronous NMOS power FET.
6
VIN
Power supply input of the regulator. Connected to the drain of the high-side NMOS power FET.
7
VIN
Power supply input of the regulator. Connected to the drain of the high-side NMOS power FET.
8
EN
Chip Enable, active high. A 2A internal pull-up current enables the device if the pin is left open.
9
PGND
Ground return of the regulator.
10
VHI
Positive supply of the high-side driver.
11
LX
Inductor drive pin. High current digital output whose average voltage equals the regulator output voltage.
12
LX
Inductor drive pin. High current digital output whose average voltage equals the regulator output voltage.
13
VDRV
Positive supply of the low-side driver and input voltage for the high-side boot strap.
14
FB
Voltage feedback input. Connected to an external resistor divider between VOUT and GND. A 125nA pull-up current
forces VOUT to VS in the event that FB is floating.
15
VREF
Bandgap reference bypass capacitor. Typically 0.1F to GND.
16
PGND
Ground return of the regulator.
