NAME

DESCRIPTION
APPLICATION INFORMATION
Synchronization input
A low impedance current input pin. The current into this pin sets
the RAMP capacitor charge current and the frequency of an
internal oscillator that provides a clock for the free-run (DC
input) mode .
Connect directly to the analog ground pin (AGND).
Connect to the gate of the low side synchronous MOSFET
through a short low inductance path.
Nominal 7V output from the internal LDO bias regulator. Locally
decouple to PGND using a low ESR/ESL capacitor located as
close to controller as possible.
Connect to negative terminal of the bootstrap capacitor and the
source terminal of the high side MOSFET.
Connect to the gate of high side MOSFET through a short low
inductance path.
Connect to the cathode of the bootstrap diode and the positive
terminal of the bootstrap capacitor. The bootstrap capacitor
supplies current to charge the high side MOSFET gate and
should be placed as close to controller as possible.
Input to the LDO bias regulator that powers internal blocks..
Input range of VBIAS is 4.5V to 30V.
Internally bonded to the die substrate. Connect to system
ground for low thermal impedance.
