ISL78220 Product details

Description

PIN # 1 2 3 4 5 6 7 8 9 10 11 SYMBOL FS SS COMP FB VREF2 GND SLOPE PLL_COMP SYNC CLK_OUT PWM_INV DESCRIPTION A resistor placed from FS to ground will set the PWM switching frequency.Use this pin to set-up the desired soft-start time.A capacitor placed from SS to ground will set up the soft-start ramp rate and in turn determine the soft-start time.The output of the transconductance amplifier.Place the compensation network between COMP and GND for compensation loop design.The inverting inp

Features

Peak current mode PWM control with adjustable slope compensation.
Precision resistor/DCR current sensing.
2-, 3-, 4- or 6-phase operation.
Adjustable phase dropping/diode emulation/pulse skipping for high efficiency at light load.
Phase dropping facilitated with companion FET driver ISL78420 (featuring tri-level input control).
Adjustable switching frequency or external synchronization from 75kHz up to 1MHz per phase.
Over-temperatu.
