Pin Function Description
These open collector/TTL compatible
inputs will program the output voltage over the ranges specified in Table 1.
Clock.
When PHASE is high, this pin puts out a clock signal synchronized
180
°
out of phase with the internal master clock. When PHASE is low, this pin
is an input for a synchronizing clock signal.
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”.
Ground B.
Ground-side current sense pin. Connect directly to low-side
MOSFET source, or to sense resistor ground.
Current Sense B.
Sensor side of current sense. Attach to low-side MOSFET
drain, or to source side of sense resistor.
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”.
High side driver source and low side driver drain switching node A.
drive return for high side MOSFET, and negative input for low-side MOSFET
current sense.
Current Sense A.
Sensor side of current sense. Attach to low-side MOSFET
drain, or to source side of sense resistor.
