UC3843BD1G Overview
This switching controller fits most application requirements since it is packaged in a 8-SOIC (0.154, 3.90mm Width) package. It is sufficient to generate 1 outputs with this dc motor controller. PMIC packaging is solid with a Tube enclosure. The system can process Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 7.6V~30V. Qualified to work in a 0°C~70°C TA dc switcher. The switching controller can be switched at Up to 500kHz. dc dc regulators can be carried out with Surface Mount. Featured in the dcdc regulator is Frequency Control which allows efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. 8 terminations with various dc switching's functions. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. Other relevant dc to dc converter ics can be found by searching "UC384*B". Total pins of switching converter are 8. Switching converter is a type of Switching Regulator or Controllers in particular. Based on the test statistics, DC regulator outputs voltage 13.4V. Voltages 25V are the maximum that the dc to dc regulator will accept. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 96 %. Having a Surface Mount makes DC switcher suitable for most application and prototype designs. Switching controllers work at 52kHz Hz. A current greater than 17mA may result in improper operation and possibly damage to the component.
