DATASHEET ISL78220 FN7688 Rev 4.00 6-Phase Interleaved Boost PWM Controller with Light Load Efficiency September 2, 2014 Enhancement The ISL78220 6-phase controller is targeted for applications Features where high efficiency (>95%) and high power are required. The Peak current mode PWM control with adjustable slope multiphase boost converter architecture uses interleaved compensation timing to multiply channel ripple frequency and reduce input and output ripple. Lower ripple results in fewer input/output Precision resistor/DCR current sensing capacitors and therefore lower component cost and smaller 2-, 3-, 4- or 6-phase operation implementation area. Adjustable phase dropping/diode emulation/pulse skipping The ISL78220 has a dedicated pin to initiate the phase for high efficiency at light load dropping scheme for higher efficiency at light load by dropping Phase dropping facilitated with companion FET driver phases based on the load current, so the switching and core ISL78420 (featuring tri-level input control) losses in the converter are reduced significantly. As the load increases, the dropped phase(s) are added back to Adjustable switching frequency or external synchronization accommodate heavy load transients and improve efficiency. from 75kHz up to 1MHz per phase Input current is sensed continuously by measuring the voltage Over-temperature/overvoltage protection across a dedicated current sense resistor or by inductor DCR. 2V 1.0% internal reference This current sensing provides precision channel-current Pb-free, 44 Ld 10x10 EP-TQFP package (RoHS compliant) balancing, and per-phase overcurrent protection. A separate -40C to +125C operating temperature range totalizing current limit function provides overcurrent protection for all the phases combined. This two-stage current protection AEC-Q100 qualified provides maximum performance and circuit reliability. Applications The ISL78220 can also provide for input voltage tracking via the VREF2 pin. The comparison reference voltage will be the Automotive power supplies lower of the VREF2 pin or the internal 2V reference. By using a -Start/stop DC/DC converter resistor network between VIN and VREF2 pin, the output - Electronic power steering systems (EPAS) voltage can track input voltage to limit the output power during automotive cranking conditions. -Fuel pumps - Injection system The ISL78220 can output a clock signal for expanding operation to 12 phases, which offers high system flexibility. Audio trunk amplifier power supplies The threshold-sensitive enable input is available to accurately Telecom and industrial power supplies coordinate the start-up of the ISL78220 with any other voltage rail.

A capacitor placed from SS to ground will set up the soft-start ramp rate and in turn determine the soft-start time. 3 COMP The output of the transconductance amplifier. Place the compensation network between COMP and GND for compensation loop design. 4 FB The inverting input of the transconductance amplifier. A resistor network should be placed between FB pin and output rail to set the output voltage. 5 VREF2 External reference input to the transconductance amplifier. When the VREF2 pin voltage drops below 1.8V, the internal reference will be shifted from 2V to VREF2. The VREF2 voltage can be programmed by connecting a resistor divider network from VCC or VIN. 6 GND Bias and reference ground for the IC. 7 SLOPE This pin programs the slope of the internal slope compensation. A resistor should be connected from SLOPE pin to GND. Please refer to Adjustable Slope Compensation on page 18 for how to choose the resistor value. 8 PLL COMP This pin serves as the compensation node for the PLL. A second order passive loop filter connected between PLL COMP pin and GND compensates the PLL feedback loop. 9 SYNC Frequency synchronization pin. Connecting the SYNC pin to an external square pulse waveform (typically 20% to 80% duty cycle) will synchronize the converter switching frequency to the fundamental frequency of the input waveform. If SYNC function is not used, tie SYNC pin to GND. A 500nA current source is connected internally to pull-down the SYNC pin if it is left open. 10 CLK OUT This pin provides a clock signal to synchronize with another ISL78220. This provides scalability and flexibility. The rising edge signal on the CLKOUT pin is in phase with the leading edge of the PWM1 signal. 11 PWM INV This pin determines the polarity of the PWM output signal. Pulling this pin to GND will force normal operation with inverting MOSFET drivers. Pulling this pin to VCC will invert the PWM signal for operation with non-inverting MOSFET drivers. This function provides the flexibility for the ISL78220 to work with different drivers.
