UC2578N Overview
With its 16-DIP (0.300, 7.62mm) package, the switching controller fits the needs of most applications. It is sufficient to generate 1 outputs with this dc motor controller. Packaged in solid enclosures, this pmic has a Tube rating. With Transistor Driver dc switching's output (s), it is able to handle it. dc control's supply and operating voltages are 14V~72V. Worked in an dc switcher with a -40°C~85°C TA rating. In this switching controller, the switch can be set to 110kHz. The Through Hole allows it to be used for dc dc regulator in general. The dcdc regulator features Current Limit, Soft Start for efficient switching control. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. A switching converters's terminal (s) sits at the DUAL position. A variety of terminations with 16 of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's voltage input is 14V. Other relevant dc to dc converter ics can be found by searching "UC2578". There are only 16 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. DC switcher's Through Hole makes it qualified for most application and prototype designs. DC switcher's120kHz is the maximum frequency of this dc regulators. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 72V. The maximum input voltage of this dc switcher is 72V, so users must limit the voltage accordingly. The supply voltage must be 14V. DC switcher will not be able to provide an output current above -800mA volts.
