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 60V. 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
> 1.35V) enables the device, and a
logic Low (V
EN
< 0.925V) 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.
