UC3845BD1R2G Overview


It comes in a 8-SOIC (0.154, 3.90mm Width) package, so switching controller can be used for most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. A solid enclosure of Tape & Reel (TR) surrounds pmic. With Transistor Driver dc switching's output (s), it is able to handle it. This dc control operates at 7.6V~30V and has a 7.6V~30V supply voltage. A 0°C~70°C TA dc switcher is not a problem. The switching controller is capable of switching at the 500kHz position. The Surface Mount value makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Terminal (s) of the switching converters are designed at the DUAL position. An array of 8 terminations of dc switching. The control methods that these dc dc converter ics use include PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "UC384*B". 8 pins are on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. DC regulator outputs 13.4V voltage according to the test statistics. This dc to dc regulator accepts only 25V input voltage at most. You should note down the dc dc regulator's usual output current of 12mA when you start a project. It is set to 48 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sThe switching controller works at a frequency of 250kHz. If the current exceeds 500μA, the component may not operate correctly and may even be damaged.
