UC3844BD1 Overview
The switching controller fits in the 8-SOIC (0.154, 3.90mm Width) package and is ideal for most applications. This dc motor controller can be used to generate outputs with 1 numbers. PMIC is packaged in a solid enclosure of Tube. A total of Transistor Driver dc switching's outputs can be handled by it. dc control's supply and operating voltages are 10V~36V. Workable in an dc switcher where 0°C~70°C TA is the 0°C~70°C TArm. This switching controller can switch at Up to 500kHz. The Surface Mount makes it ideal for general dc dc regulator. For efficient switching control, the dcdc regulator features Frequency Control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Terminal (s) of the switching converters are designed at the DUAL position. Various 8 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. There is a DC switcher's nominal voltage of 15V. Other relevant dc to dc converter ics can be found by searching "UC384*B". The switching converter has a total of 8 pins. Switching converter is a special type of Switching Regulator or Controllers. DC regulator outputs 5.1V voltage according to the test statistics. This dc to dc regulator accepts only 25V input voltage at most. 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. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 48 % during power-up and power-down. In most applications and prototype designs, DC switcher is qualified as a Surface Mount. Switching controller operates at 275kHz Hz. DC switching uses 12mA when it is dormant.
