Pin Function Description
Voltage Identification Code Inputs.
inputs will program the output voltage over the ranges specified in Table 1. Pull-
up resistors are internal to the controller.
7.5V Rail.
Bypass this pin with a 0.1
μ
F ceramic capacitor to AGND.
Analog Ground.
Return path for low power analog circuitry. This pin should be
connected to a low impedance system ground plane to minimize ground loops.
Low Side FET Driver for B.
Connect this pin to the gate of an N-channel
MOSFET for synchronous operation. The trace from this pin to the MOSFET gate
should be <0.5
ó
.
Power Ground B.
Return pin for high currents flowing in low-side MOSFET.
Connect directly to low-side MOSFET source.
High side driver source and low side driver drain switching node B.
drive return for high side MOSFET, and negative input for low-side MOSFET
current sense.
High Side FET Driver B.
Connect this pin to the gate of an N-channel MOSFET.
The trace from this pin to the MOSFET gate should be <0.5
Bootstrap B.
Input supply for high-side MOSFET.
Bootstrap A.
Input supply for high-side MOSFET.
High Side FET Driver A.
Connect this pin to the gate of an N-channel MOSFET.
The trace from this pin to the MOSFET gate should be <0.5

VCC.
Internal IC supply. Connect to system 12V supply, and decouple with a
0.1
μ
F ceramic capacitor.
Power Good Flag.
An open collector output that will be logic LOW if the output
voltage is not within +/-10% of the nominal output voltage setpoint.
