UC3578DPG4 Overview
In the 16-SOIC (0.154, 3.90mm Width) package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 1. A solid enclosure of Tube surrounds pmic. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 14V~72V voltage are supplied and operated. Qualified to work in an dc switcher with 0°C~70°C TA. Using this switching controller, it is possible to switch at 110kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Featured in the dcdc regulator is Current Limit, Soft Start which allows efficient switching control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminals (s) are designed at DUAL. Different dc switching's functions can be applied to 16 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. It is inputted with a DC switcher's voltage of 14V. UC3578 can be searched for other relevant dc to dc converter ics. Switching converter has a total of 16 pins. Switching converter is a special type of Switching Regulator or Controllers. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. This dc regulatorhas a max frequency of 120kHz. To operate the voltage regulator dc to dc safely and reliably, users should apply 72V. The dc switcher's maximum input voltage is 72V; users must limit it accordingly. Voltage 14V must be supplied. An output current greater than -800mA cannot be provided by the dc switcher.
