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) + 33 [V(CSIN+) – V(CSIN-)].
Connecting all ILL pins together creates a bus which provides an indication of the
average current being supplied by the power supply. 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.
Digital Power State Indicator input, active low.
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 at switching frequency.
Communication input from phase IC(s) statically floats at VCCL/2. Momentarily
pulling pin up to VCCL indicates a phase has entered the daisy chain loop resulting
in an up-shift in the CLKOUT frequency. Momentarily pulling down to ground
indicates a loss of a phase and down-shifts the CLKOUT frequency.
Phase clock output at switching frequency.
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.
Programs cycle by cycle Over Current threshold voltage. V(OCSET) gets compared
against the V(SW) node when the high side MOSFET is on. If V(SW) gets below
V(OCSET), the next switch pulse gets skipped to allow inductor relaxation. The
V(OCSET) threshold is programmed by forcing a 200uA current sink through an
external resistor kelvined to the drain of the high side FET.
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).
Output of the Current Sense Amplifier is connected to this pin through a 3k
resistor. Voltage on this pin is equal to V(DACIN) + 33 [V(CSIN+) – V(CSIN-)].
Connecting all ISHARE pins together creates a share bus which provides an
indication of the average current being supplied by active phases only. The pin
becomes high impedance during PSI# activation.
