Pin Description (Continued)

Pin Name Pin Function

Number

Switch Node (Input): High current output driver return. The SW pin connects directly to the switch node.

Due to the high speed switching on this pin, the SW pin should be routed away from sensitive nodes.

Current Sense (Input): SW pin also senses the current by monitoring the voltage across the low-side

MOSFET during OFF-time. The current sensing is necessary for short circuit protection. In order to

sense the current accurately, connect the low-side MOSFET drain to SW using a Kelvin connection.

Boost (Output): Bootstrapped voltage to the high-side N-channel MOSFET driver. A Schottky diode is

connected between the VDD pin and the BST pin. A boost capacitor of 0.1μF is connected between the

BST pin and the SW pin. Adding a small resistor at BST pin can slow down the turn-on time of high-side

N-Channel MOSFETs.

BST

Thermal Pad and Signal ground. GND is the ground path for VDD and the control circuitry. The loop for

the signal ground should be separate from the power ground (PGND) loop.
