UC3845ADWTR Overview


Capsuled in the 16-SOIC (0.295, 7.50mm Width) package, the switching controller can be used for a wide range of applications. 1 outputs can be generated with the dc motor controller. A solid enclosure of Tape & Reel (TR) surrounds pmic. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 7.6V~30V are the dc control's supply voltage and operating voltage, respectively. A 0°C~70°C TA dc switcher is not a problem. With this switching controller, you can switch at 500kHz. The Surface Mount value makes it suitable for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. There are a terminal (s) on the switching converters that are designed at DUAL. 16 terminations with various dc switching's functions. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. Searching "UC3845" will return other relevant dc to dc converter ics. There are a total of 16 pins on switching converter. Switching converter is a special type of Switching Regulator or Controllers. According to the test statistics, DC regulator outputs 15V voltage. You should note that the dc dc regulator's usual output current is 200mA. A duty cycle set at 50 % ensures voltage regulator dc to dc reliability during power-on and power-off. There is 450kHz frequency setting on the switching controller. Users should apply 30V to operate the voltage regulator dc to dc safely and reliably. A nominal working status is achieved when the input voltage is set to 25V.
