High-side driver output and input to GATEL non-overlap comparator.
Supply for high-side driver. An internal bootstrap synchronous PFET is connected
between this pin and the VCCP pin.
Supply for low-side driver. An internal bootstrap synchronous PFET is connected
from this pin to the BOOST pin.
Low-side driver output and input to GATEH non-overlap comparator.
Return for low side driver and reference for GATEH non-overlap comparator.
Local Ground for internal circuitry and the IC substrate connection.
Non-Inverting input to the current sense amplifier and input to debug comparator.
Inverting input to the current sense amplifier and input to synchronous rectification
disable comparator.
Enable input. A logic low applied to this pin puts the IC into fault mode. Do not float
this pin as the logic state will be undefined.
Open drain output that drives low during startup and under any external fault
condition. Connect external pull-up.
Tri-state input with internal pull-up to 1.425 V. Low/High voltage shifts the Error
Amplifier reference voltage Up/Down 5%. V(MARGIN) should not be biased to a
voltage greater than V(VCCL).
Inverting remote sense amplifier input. Connect to ground at the load.
Non-inverting remote sense amplifier input. Connect to output at the load.
Output of the voltage regulator, power input for clock oscillator circuitry and other
internal circuitry. Connect a decoupling capacitor to LGND.
Remote sense amplifier output.
Over voltage sense input during normal operation.
Inverting input to the Error Amplifier.
Output of the Error Amplifier.
Average current input signal from active and inactive phase IC(s). This pin is also
used to communicate an over voltage condition to the phase IC(s).
An external resistor tied to VREF along with a fixed internal current source
programs the constant output current limit and hiccup over-current thresholds.
Over-current protection can be disabled by programming the threshold higher than
the possible signal on the IIN pin, but no greater than 5V (do not float this pin).
Reference voltage for the Error Amplifier. An external RC network to LGND
programs the margin slew rate and compensates the internal buffer amp.
An external capacitor to LGND programs converter startup and over current
protection delay timing. It is also used to compensate the constant output current
loop during soft start.
