UC3845BN Overview


As a result of 8-DIP (0.300, 7.62mm) compact design, the switching controller is compatible with most applications. 1 outputs can be generated with the dc motor controller. The pmic is packaged in Tube solid enclosure. The program can handle Transistor Driver dc switching's outputs (s). DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. Worked in a 0°C~70°C TA dc switcher before. In this switching controller, the switch can be set to 500kHz. The Through Hole value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Frequency Control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. There are a terminal (s) on the switching converters that are designed at DUAL. The 8 terminations can be used for a wide range of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis set to 15V. In addition to "UC384*B", there are other relevant dc to dc converter ics you can find. There are 8 pins on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. DC regulator outputs 5.1V voltage according to the test statistics. The dc to dc regulator can only accept 25V input voltage. In most cases, the output current of the dc dc regulator will be 1A, so note that when you start the project. A duty cycle set at 48 % ensures voltage regulator dc to dc reliability during power-on and power-off. DC switcher's Through Hole qualifies it for most applications and prototypes. A frequency of 275kHz is set for the switching controller. DC switchings that are dormant use 12mA.
