Supply rail for the floating top gate driver. To form a boost circuit, use an external diode to bring the desired
input voltage to this pin (cathode connected to BOOT pin). Connect a capacitor (C
the LX pin. Typical values for C
Switch node pin. This is the reference for the floating top gate driver. Connect this pin to the source of the top
MOSFET.
Top gate MOSFET driver pin. Connect this pin to the gate of the top N−channel MOSFET.
Bottom gate MOSFET driver pin. Connect this pin to the gate of the bottom N−channel MOSFET.
IC ground reference. All control circuits are referenced to this pin.
Supply rail for the internal circuitry. Operating supply range is 4.5 V to 13.2 V. Decouple with a 1 mF capacitor
to GND. Ensure that this decoupling capacitor is placed near the IC.
Compensation Pin. This is the output of the error amplifier (EA) and the non−inverting input of the PWM com-
parator. Use this pin in conjunction with the FB pin to compensate the voltage−control feedback loop. Pull this
pin low for disable.
This pin is the inverting input to the error amplifier. Use this pin in conjunction with the COMP pin to com-
pensate the voltage−control feedback loop. Connect this pin to the output resistor divider (if used) or directly
to V
