UC2844AN Overview
With its 8-DIP (0.300, 7.62mm) package, the switching controller fits the needs of most applications. 1 outputs can be generated with the dc motor controller. Packaged in solid enclosures, this pmic has a Tube rating. A total of Transistor Driver dc switching's outputs can be handled by it. dc control's supply and operating voltages are 10V~30V. Qualified to work in an dc switcher with -25°C~85°C TA. With this switching controller, you can switch at Up to 500kHz. As it has a Through Hole value, it can be used for general dc dc regulator. Switching control is made easier with the dcdc regulator's Frequency Control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. A switching converters's terminal (s) sits at the DUAL position. A variety of dc switching's functions can be performed on 8 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. You can find other relevant dc to dc converter ics by searching "UC2844". The type is a particular Switching Regulator or Controllers of switching converter. A 15V voltage of DC regulator was detected in the test statistics. A maximum voltage of 30V is accepted by the dc to dc regulator as an input voltage. It's important to remember that the dc dc regulator's normaloutput current is 1A, so you should note it down when starting a new project. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. Having a Through Hole makes DC switcher suitable for most application and prototype designs. Switching controller operates at 500kHz Hz. An input flow rate of 11mA could satisfy the switching converter 's operation requirements.
