Description

Pin name

for 15W 3-Coil

MP-A13 transmitter

GND

Ground. Connect directly to the EPAD and to ground plane.

Positive input of input current sense amplifier (DC-DC). Connect to

the positive terminal of the input current sense resistor. Use a

dedicated (Kelvin) connection.

CSPI_0

Negative input of input current sense amplifier t (DC-DC). Connect to

the negative terminal of the input current sense resistor. Use a

dedicated (Kelvin) connection.

Bootstrap power supply for buck (DC-DC) high side gate driver.

Connect a capacitor (recommended value 0.1µF) from this pin to

SW1_0. Also, connect a Schottky diode from VDDD to BST1_0.

CSNI_0

BST1_0

High-side gate driver output of buck converter (DC-DC bank 1).

Connect to the buck high-side FET gate. Use a wide trace to minimize

inductance of this connection.

Exposed ground pad. Connect directly to ground plane and pins 34

and 64.
