ISL6440IAZ Overview
In the QSOP package, the switching controller meets most application requirements. For 2 outputs, the dc motor controller is appropriate. The switching controller can be switched at 300kHz. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. The switching converters's terminal (s) are designed at DUAL . Various 24 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. 24 pins are present on switching converter. There is a particular type of Switching Regulator or Controllers in switching converter. It is recommended to use 5.6V as the minimum input voltage of dc dc voltage regulator. A duty cycle set at 93 % ensures voltage regulator dc to dc reliability during power-on and power-off. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. To operate the voltage regulator dc to dc safely and reliably, users should apply 12V. Temperatures should be kept at -40°C or higher. There should be 85°C temperature above 85°C degrees Celsius when dc regulator runs. In total, thare switch converters have 1 functions. The dc switching utilizes 50μA when it is in a dormant state. A voltage regulators switching with 24 pins is designed. The controller can switch at the maximum frequency of 340kHz. A 60mA input is ideal for this application. It outputs a voltage of 24V when working normally. There is a 4mA volt supply current.
