Pin Description (Continued)
Pin
Name
Function
13
V
IN
Main power supply pin.
14
NC
No internal connection.
15
FPWM
When FPWM is high, pulse-skipping mode operation at light load is disabled. The
converter is forced to operate in constant frequency mode.
16
PGND
Power ground.
17
LDRV
Low-side gate-drive output.
18
CBOOT
Bootstrap capacitor connection for high-side gate drive.
19
SW
Switched-node connection, which is connected with the source of the high-side
MOSFET.
20
HDRV
High-side gate-drive output. HDRV is a floating drive output that rides on SW voltage.
