                                                ISL6440IAZ-T7 Overview
Capsuled in the QSOP package, the switching controller can be used for a wide range of applications. 2 outputs can be generated with the dc motor controller. With this switching controller, you can switch at 300kHz. Total pins of switching converter are 24. It is set to 93 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. Users should apply 24V to operate the voltage regulator dc to dc safely and reliably. A temperature -40°C lower than -40°C should be maintained. A temperature of 85°C degrees Celsius is recommended. 340kHz is the maximum frequency at which the controller can switch. Inputs of 60mA are ideal for this component. normalworking processes output 5.5V voltage. There is a 4mA volt supply current.
