Pin Function
Supply Voltage (Input): 3V to 14.5V.
5V Internal Linear Regulator (Output): V DD is the external MOSFET gate
drive supply voltage and an internal supply bus for the IC. When V IN is <5V,
this regulator operates in dropout mode.
Current Sense (Input): Current-limit comparator noninverting input. The cur-
rent limit is sensed across the MOSFET during the ON time. The current can
be set by the resistor in series with the CS pin.
Compensation (Input): Pin for external compensation. .
Feedback (Input): Input to error ampli ? er. Regulates error ampli ? er to 0.8V.
Ground (Return).
Low-Side Drive (Output): High-current driver output for external synchro-
nous MOSFET.
Switch (Return): High-side MOSFET driver return.
High-Side Drive (Output): High-current output-driver for the high-side MOS-
FET. When V IN is between 3.0V to 5V, 2.5V threshold MOSFETs should be
used. At V IN > 5V, 5V threshold MOSFETs should be used.
Boost (Input): Provides the drive voltage for the high-side MOSFET driver.
The gate-drive voltage is higher than the source voltage by V IN minus a
diode drop.
