PIN DESCRIPTION
Non-inverting input to Ramp Comparator
Inverting input to Ramp Comparator
Inverting input to VRHOT comparator. Connect resistor divider from VBIAS to LGND
to program VRHOT threshold. Diode or thermistor may be substituted for lower
resistor for enhanced/remote temperature sensing.
Open Collector output of the VRHOT comparator which drives low if IC junction
temperature exceeds the user programmable limit. Connect external pull-up.
Output of the Current Sense Amplifier and input to the Share Adjust Error Amplifier.
Voltage on this pin is equal to V(DACIN) + 34 * [V(CSIN+) – V(CSIN-)]. Connecting
ISHARE pins together creates a Share Bus enabling current sharing between Phase
ICs. The Share bus is also used by the Control IC for voltage positioning and Over-
Current protection.
Compensation for the Current Share control loop. Connect a capacitor to ground to
set the control loop’s bandwidth.
PWM comparator input from the error amplifier output of Control IC. Both Gate
Driver outputs drive low if the voltage on this pin is less than 91% of V(DACIN).
PWM comparator ramp input. Connect a resistor from this pin to the converter input
voltage and a capacitor to LGND to program the PWM ramp.
Signal ground and IC substrate connection
Power for internal circuitry
Power for Low-Side Gate Driver
Low-Side Gate Driver Output and input to GATEH non-overlap comparator
Return for Gate Drivers
High-Side Gate Driver Output and input to GATEL non-overlap comparator
Power for High-Side Gate Driver
Non-inverting input to the Current Sense Amplifier
Inverting input to the Current Sense
Open Collector output of the Phase Fault comparator. Drives low if Phase current is
unable to match the level of the SHARE bus due to an external fault. Connect
external pull-up.
Reference voltage input from the Control IC. Current sensing and PWM operation
referenced to this pin.
System reference voltage for internal circuitry
