Pin Function Description
Voltage Identification Code Inputs. Internally pulled-up open collector/TTL
compatible inputs program the output voltage over range specified in Table 1.
5V Rail. Bypass this pin with a 0.1µF 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 optimally be <0.5".
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. Gate
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 optimally 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 optimally be <0.5".
High Side Driver Source and Low Side Driver Drain Switching Node A. Gate
drive return for high side MOSFET, and negative input for low-side MOSFET
current sense.
Power Ground A. Return pin for high currents flowing in low-side MOSFET.
Connect directly to low-side MOSFET source.
Low Side FET Driver for A. Connect this pin to the gate of an N-channel
MOSFET for synchronous operation. The trace from this pin to the MOSFET gate
should optimally be <0.5".
VCC. Internal IC supply. Connect to system 12V supply, and decouple with a 10
resistor and 1µF ceramic capacitor.
Power Good Flag. An open collector output that will be logic LOW if the output
voltage is less than 350mV less than the nominal output voltage setpoint. Power
Good is prevented from going low until the output voltage is out of spec for
500µsec.
