DESCRIPTION

ADDR0

3

Sets low-order 3-bits of the PMBus address. Connect a resistor between this pin and AGND.

ADDR1

2

Sets high-order 3-bits of the PMBus address. Connect a resistor between this pin and AGND.

AGND

38

Analog ground return for controller device. Connect to GND at the thermal tab.

BP3

27

Output of the 3.3-V on-board regulator. This regulator powers the controller and should be bypassed with a

minimum of 2.2 µF to AGND. BP3 is not designed to power external circuit.

BP6

28

Output of the 6.5-V on-board regulator. This regulator powers the driver stage of the controller and should

be bypassed with a minimum of 2.2 µF to GND. TI recommends using an additional 100-nF typical bypass

capacitor for reduce ripple on BP6.

BOOT

7

Bootstrap pin for the internal flying high-side driver. Connect a typical 100-nF capacitor from this pin to the

SW pin.

CLK

5

PMBus CLK pin. See Supported PMBus Commands section.

CNTL

1

PMBus CNTL pin. See Supported PMBus Commands section. The CNTL pin has an internal pull-up and

floats high when left floating.

COMP

35

Output of the error amplifier. Connect compensator network from this pin to the FB pin.
