PIN DESCRIPTION
Output of the Current Sense Amplifier is connected to this pin through a 3k
resistor. Voltage on this pin is equal to V(DACIN) + 32.5 [V(CSIN+) – V(CSIN-)].
Connecting all ISHARE pins together creates a share bus which provides an
indication of the average current being supplied by all the phases. The signal is used
by the Control IC for voltage positioning and over-current protection. OVP mode is
initiated if the voltage on this pin rises above V(VCCL)- 0.8V.
Reference voltage input from the Control IC. The Current Sense signal and PWM
ramp is referenced to the voltage on this pin.
Ground for internal IC circuits. IC substrate is connected to this pin.
Phase clock input.
Phase clock output.
Clock input.
Return for low side driver and reference for GATEH non-overlap comparator.
Low-side driver output and input to GATEH non-overlap comparator.
Supply for low-side driver. Internal bootstrap synchronous PFET is connected from
this pin to the BOOST pin.
Supply for high-side driver. Internal bootstrap synchronous PFET is connected
between this pin and the VCCL pin.
High-side driver output and input to GATEL non-overlap comparator.
Return for high-side driver and reference for GATEL non-overlap comparator.
Supply for internal IC circuits.
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.
PWM comparator input from the error amplifier output of Control IC. Body Braking
mode is initiated if the voltage on this pin is less than V(DACIN).
