Pin Descriptions
Pin
Name
Description
Application Information
1
SW
Switch pin
Attaches to the switch node.
2
VIN
Source input voltage
Input to the regulator. Operates from 4.5V to 42V.
3
BOOT
Bootstrap input
Provides the gate voltage for the high side NFET.
4
GND
System ground
Provide good capacitive decoupling between VIN and this pin.
5
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.
6
FB
Feedback pin
Inverting input to the internal voltage error amplifier.
7
EN
Precision enable pin
When pulled low regulator turns off.
