UC3844AD Overview
Capsuled in the 14-SOIC (0.154, 3.90mm Width) package, the switching controller suits most application needs. dc motor controller is suitable for 1 output generation. The pmic is packaged in Tube solid enclosure. With this function, you can deal with Transistor Driver dc switching's outputs (s). Voltages 10V~30V are the dc control's supply voltage and operating voltage, respectively. Qualified to work in an dc switcher with 0°C~70°C TA. With this switching controller, you can switch at Up to 500kHz. Surface Mount makes it suitable for general dc dc regulator. To provide efficient switching control, Frequency Control is included in the dcdc regulator. SWITCHING CONTROLLER analog IC connects the switch converters. Thare switching converters has a terminal (s) at DUAL . An array of 14 terminations of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. UC*84 can be used to locate other relevant dc to dc converter ics. There are a total of 14 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. Based on the test statistics, DC regulator outputs voltage 15V. The dc to dc regulator is limited to 30V input voltage. The dc dc regulator's usual output current is 200mA, which should be noted down when you start a project. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. This Surface Mount makes DC switcher suitable for most prototypes and applications. Switching controller operates at a frequency of 500kHz. Dormant dc switchings use 11mA. It could be possible to satisfy the switching converter for operation with a current flow input of 11mA.
