Pinout and package

PackageQFN-20 (3mmx5mmx1.6mm)

PinNameFunctionSource
1FB- Feedback. Connect to the tap of an external resistor divider to set the output voltage.
2VCC- Internal 5V LDO output. No external capacitor needed.
3AGND- Analog ground. Reference ground of the logic circuit. Connect to PGND on PCB layout.
11BST- Bootstrap. Bootstrap capacitor is integrated internally. No external connections needed.
16IN- Supply voltage. Supplies power for the internal MOSFET and regulator.
17EN/SYNC- Enable/Sync. High to enable, apply external clock to change frequency.
18PG- Power good indicator. Open drain structure.
10, 15, 19, 20NC- DO NOT CONNECT. Must be left floating.
12, 13, 14PGND- Power ground. Reference ground of the power device.
4, 5, 6SW- Switch Output. No connection needed, large copper plane recommended for heat sink.
7, 8, 9OUT- Power output. Connect the load to OUT. An output capacitor is needed.
