Description
Current sense input pin. Voltage generated across an external sense resistor is fed
into this pin.
Compensation pin. A resistor-capacitor combination connected to this pin provides
compensation for the control loop. Pull this pin below 0.65V to shutdown.
Feedback pin. The output voltage should be adjusted using a resistor divider to
provide 1.270V at this pin.
Ground pin.
Switch Node. Source of the external MOSFET is connected to this node.
Drive pin. The gate of the external MOSFET should be connected to this pin.
Boot-strap pin. A capacitor must be connected between this pin and SW pin (pin 5)
for proper operation. The voltage developed across this capacitor provides the gate
drive for the external MOSFET.
Power Supply Input pin.
