IR3510
“VFB” (PIN#15): Voltage feedback input. It is internally connected to the inverting input of the voltage error
amplifier.
“IREF” (PIN#16): Voltage error amplifier output. It is also the current reference input to the current error amplifier.
It is clamped by the “OCSET” voltage when it is running in constant current limit mode.
“IGAIN” (PIN#17): Inverting input to the current report amplifier. Connect a resistor network between this pin and
the “IO” pin to program the current report amplifier gain.
“IO” (PIN#18): Current report amplifier output representing the output load current. In order to measure negative
output current in a paralleling system, a fixed 200mv input offset voltage is added to the current report amplifier. At
no load, it reports this offset voltage, which is amplified by the current report gain.
“IFB” (PIN#19): Current feedback input. It is internally connected to the inverting input of the current error
amplifier. The output of “IO” pin is connected to this pin through a resistor.
“EAOUT” (PIN#20): Current error amplifier output. Connect it to the “EA” pin of the phase IC to control the PWM
duty cycle.
“IIN” (PIN#21): Current sense input from the phase IC. It has an offset voltage of “VREF” voltage. Connect it to the
“ISHARE” pin of the phase IC.
“RMPOUT” (PIN#22): Oscillator triangle waveform output. Connect it to the “RMPIN” pin of the phase IC to set the
switching frequency and phase timing. The frequency of this ramp signal is programmed by the resistor connected
to the “ROSC” pin.
“VREF” (PIN#23): Buffered output of “VSET” voltage. Connect it to the “DACIN” pin of the
phase IC to set the
“IIN” offset voltage and the PWM ramp floor voltage.
“ROSC” (PIN#24): Connect an external resistor to program the switching frequency. The lower the resistor value,
the higher the switching frequency. The voltage on this pin can be used as a voltage reference with 1% tolerance.
It is 1.230V typical with Rosc = 42K.
“OR-” (PIN#25): Oring comparator inverting input. Connect it to the DRAIN side of the Oring FET through a
programming resistor. A constant current source flowing out of this pin goes through that programming resistor to
set the reverse current cut-off threshold.
“OR+” (PIN#26): Oring comparator non-inverting input. Connect it to the SOURCE side of the Oring FET.
“GATE_O” (PIN#27): Oring FET gate driver output. It is driven by the internal charge-pump with 10uA charging
and 2A discharging currents. It also has internal 3k resistor pulled-up to VIN to speed up the turn-on of Oring FET.
“LGND” (PIN#28): Local GND for Internal circuit and IC substrate connection.
“GATE_I” (PIN#29): Input FET driver output. It is driven by the internal charge-pump with 20uA charging and 2A
discharging currents.
