Pin Function
Bootstrap capacitor connection node for high-side gate driver. Connect a 0.1F
ceramic capacitor from BOOT to SW to power the internal gate driver.
Supply voltage input, 5.2V to 80V. Bypass VIN to GND with a large high-quality
capacitor.
Switch node for output inductor connection.
Power ground. The exposed pad must be connected to GND and well soldered
to the input and output capacitors and a large PCB copper area for maximum
power dissipation.
Feedback voltage input. Connect FB to the midpoint of the external feedback
resistor divider to sense the output voltage. The device regulates the FB voltage
at 0.8V (typical) Feedback Reference Voltage.
Compensation node for the compensation of the regulation control loop.
Connect a series RC network from COMP to GND. In some cases, another
capacitor from COMP to GND may be required.
Enable control input. A logic High (V
EN
> 1.3V) enables the device, and a logic
Low (V
EN
< 0.875V) shuts down the device, reducing the supply current to 3A
or below. Connect EN pin to VIN pin with a 100k pull-up resistor for automatic
startup.
Soft-start capacitor connection node. Connect an external capacitor from SS to
GND to set the soft-start time. Do not leave SS pin unconnected. A capacitor of
capacitance from 10nF to 100nF is recommended, which can set the soft-start
time from 1.33ms to 13.3ms, accordingly.
