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 BST pin). Connect a capacitor (C
and the PHASE pin. Typical values for C
Top gate MOSFET driver pin. Connect this pin to the gate of the top N−Channel MOSFET.
IC ground reference. All control circuits are referenced to this pin.
Bottom gate MOSFET driver pin. Connect this pin to the gate of the bottom N−Channel MOSFET.
Supply rail for the internal circuitry. Operating supply range is 4.5 V to 15 V. Decouple with a 1 mF
capacitor to GND. Ensure that this decoupling capacitor is placed near the IC.
This pin is the inverting input to the error amplifier. Use this pin in conjunction with the COMP pin to
compensate the voltage−control feedback loop. Connect this pin to the output resistor divider (if used) or dir-
ectly to Vout.
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. The com-
pensation capacitor also acts as a soft−start capacitor. Pull this pin low with an open drain transistor for disable.
Switch node pin. This is the reference for the floating top gate driver. Connect this pin to the source of the top
MOSFET.
