Pin Descriptions
Pin
Name
Description
Application Information
1
BOOT
Bootstrap input
Provides the gate voltage for the high side NFET.
2
SS
Soft-start pin
An external capacitor and an internal 50 A current source set the time
constant for the rise of the error amplifier reference. Pin can be left floating
and internal soft-start will be default.
3
RT/SYNC Oscillator frequency adjust pin or
frequency synchronization
A resistor connected from this pin to GND adjusts the oscillator frequency.
This pin can also accept an input for synchronization from an external
clock. Pin can be left floating and internal setting will be default to 500 kHz.
4
FB
Feedback pin
Inverting input to the internal voltage error amplifier.
5
EN
Precision enable pin
When pulled low regulator turns off.
6
GND
System ground
Provide good capacitive decoupling between VIN and this pin.
7
VIN
Source input voltage
Input to the regulator. Operates from 4.5V to 42V.
8
SW
Switch pin
Attaches to the switch node.
