Pin Description
Pin
Name
Function
1, 2
SW
Switched-node connection, which is connected with the source of the internal high-side
MOSFET.
3-5
VIN
Main power supply pin.
6
VCB
Bootstrap capacitor connection for high-side gate drive.
7
AVIN
Input supply voltage for control and driver circuits.
8
SD(SS)
Shutdown and Soft-start control pin. Pulling this pin below 0.3V shuts off the regulator. A
capacitor connected from this pin to ground provides a control ramp of the input current.
Do not drive this pin with an external source or erroneous operation may result.
9
FB
Output voltage feedback input. Connected to the output voltage.
10
COMP
Compensation network connection. Connected to the output of the voltage error amplifier.
11
NC
No internal connection.
12-13
AGND
Low-noise analog ground.
14-16
PGND
Power ground.
