Connect a bootstrap capacitor (Typically from 0.1 to 0.47 μF) from this pin to PHASE pin to create a BOOT voltage suitable to drive a standard N-Channel MOSFET.

2 UGATE

Upper-gate drive pin. Connect this pin to the upper MOSFET gate providing the gate drive. This pin is monitored by the adaptive shoot -through protection circuitry to determine when the upper MOSFET has been turned off. 3 OPS Over-current setting pin. Connecting a resistor (R OCSET) between OPS and GND to set the over-current trigger point.

4 LGATE

Lower-gate drive pin. Connect LGATE to the lower MOSFET gate providing the gate drive for the lower MOSFET. This pin is monitored by the adaptive shoot-through protection circuitry to determine when the lower MOSFET has been turned off. 5 VCC Bias supply pin. Provides a 5V or 12V bias supply for the chip from this pin. The pin should be bypassed with a capacitor to GND. 6 FB Feedback pin. This pin is the inverting input of the internal error amplifier. A resistor divider from output to GND is used to set the output voltage.

7 REFIN

External reference input pin. This pin receives a voltage with range from 0.4V to 3.0V as the reference voltage at the non-inverting input of the error amplifier. Pull this pin lower than 0.3V to disable the controller, and the V UGATE and VLGATE will go low. Let this pin open for internal 0.6V reference use.

8 PHASE

PHASE pin. This pin connects to the source of the upper MOSFET and the drain of the lower MOSFET. This pin is also monitored by the adaptive shoot -through protection circuitry to determine when the upper MOSFET is turned off. 9 GND Exposed pad as ground pin. Represents the signal and power ground for the IC. Tie this pin to ground island/plane through the lowest impedance connection available.
