MK06A
Boost voltage that drives the internal NMOS control switch. A
bootstrap capacitor is connected between the BOOST and SW pins.
Signal and Power ground pin. Place the bottom resistor of the
feedback network as close as possible to this pin for accurate
regulation.
Feedback pin. Connect FB to the external resistor divider to set output
voltage.
Enable control input. Logic high enables operation. Do not allow this
pin to float or be greater than V
Input supply voltage. Connect a bypass capacitor to this pin.
Output switch. Connects to the inductor, catch diode, and bootstrap
capacitor.
