Name
Package Name
Function
QFN3x3-16L SOP-8(EP)
PGND 1, 2, 3 2 Main power ground pin.
FB 4 3 Feedback voltage to internal error amplifier, the threshold voltage is 0.6V.
GND 5 4 Signal ground for small signal components.
NC 6, 16 — No connection.
EN 7 5
Enable control input. Force this pin voltage above 1.5V, enables the chip, and
below 0.3V shuts down the device.
TEST 8 6 Test Mode(no connect or to Ground).
VIN 9 7 Bias supply. Chip main power supply pin.
PVIN 10, 11, 12 8 Input supply for power stage. Must be closely decoupled to PGND.
SW 13, 14, 15 1 The drains of the internal main and synchronous power MOSFET.
