Type
Function
9 Vin S Input voltage for Internal LDO. A 1.0µF capacitor should be connected
between this pin and PGnd. If external supply is connected to Vcc/LDO_out
pin, this pin should be shorted to Vcc/LDO_out pin.
10 Vcc/LDO_Out I/O Input Bias for external Vcc Voltage/ output of internal LDO. Place a minimum
2.2µF cap from this pin to PGnd
11 PGnd S Power Ground. This pin serves as a separated ground for the MOSFET
drivers and should be connected to the system's power ground plane.
12 SW O Switch node. This pin is connected to the output inductor.
13 PVin S Input voltage for power stage.
14 Boot I Supply voltage for high side driver, a 100nF capacitor should be connected
between this pin and SW pin.
15 Enable I Enable pin to turn on and off the device, if this pin is connected to PVin pin
through a resistor divider, input voltage UVLO can be implemented.
16 NC - Do Not Connect. Must be left floating.
17 GND S Signal ground for internal reference and control circuitry.
