UC3842BDG Overview


With its 14-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. This dc motor controller can be used to generate outputs with 1 numbers. An enclosure of Tube is used to package the PMIC. Transistor Driver dc switching's outputs (s) are supported. dc control's supply and operating voltages are 10V~30V. Worked in a 0°C~70°C TA dc switcher before. With this switching controller, you can switch at Up to 500kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Frequency Control is used for efficient switching control in the dcdc regulator. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at DUAL . 14 terminations with a variety of function. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. You can find other relevant dc to dc converter ics by searching "UC384*B". Total pins of switching converter are 14. Particularly, switching converter is a type of Switching Regulator or Controllers. Statistically, the DC regulator outputs 13.4V voltage. Considering the dc to dc regulator can only accept 25V input voltage, it is important to take note of this. A starting point for a project is to note down the dc dc regulator's usual output current, which is 12mA. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 96 % during power-up and power-down. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. Switching controller operates at 250kHz Hz.
