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, short
VDD to the input supply through a 10 ? resistor.
Current Sense (Input): Current-limit comparator noninverting input. The current
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 / Enable (Input): Dual function pin. Pin for external compensation.
If this pin is pulled below 0.25V, with the reference fully up the device shuts
down (50 μ A typical current draw).
Feedback (Input): Input to error amplifier. Regulates error amplifier to 0.8V.
Ground (Return).
Low-Side Drive (Output): High-current driver output for external synchronous
MOSFET.
Switch (Return): High-side MOSFET driver return.
High-Side Drive (Output): High-current output-driver for the high-side MOSFET.
When V IN is between 3.0V to 5V, 2.5V threshold MOSFETs should be used. At
V IN > 5V, 4.5V 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 DD minus a diode drop.
Connect to Ground.
