ISL6439AIRZ Overview


With its VQFN package, the switching controller fits the needs of most applications. For 1 outputs, the dc motor controller is appropriate. In this switching controller, the switch can be set to 650kHz. The switch converters are connected to a SWITCHING CONTROLLER analog IC. Thare switching converters has a terminal (s) at QUAD . An array of 16 terminations of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input of 3.3V. The type is a particular Switching Regulator or Controllers of switching converter. A maximum voltage of 3.465V is accepted by the dc to dc regulator as an input voltage. The maximum duty cycle of this voltage regulator dc to dc is set to 100 % to ensure reliability during power-up and power-down. Having a Surface Mount makes DC switcher ideal for most prototype and application designs. In order for the voltage regulator dc to dc to perform safely and reliably in a circuit, users are advised to apply 3.3V. The temperature should be at least -40°C. The temperature should not exceed 85°C degrees Celsius. 1 functions (s) are included in the switch converters. There is a design for voltage regulators switching with 16 pins. At maximum frequency, the controller can switch at 650kHz. A 2A input is ideal for this application. When it is working normally, it outputs a value of 3.3V.
