UC3845BVDR2 Overview
With a 14-SOIC (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. 1 outputs are supported by the dc motor controller. The pmic is packaged in Tape & Reel (TR) solid enclosure. The program can handle Transistor Driver dc switching's outputs (s). 7.6V~30V is the operating voltage and supply voltage of the dc control. Qualified to work in an dc switcher with -40°C~105°C TA. Using this switching controller, it is possible to switch at 500kHz. A generalization of dc dc regulator can be made using Surface Mount. For efficient switching control, the dcdc regulator features Frequency Control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. There are a terminal (s) on the switching converters that are designed at DUAL. An array of 14 terminations of dc switching. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. The nominal DC switcher's voltage input is 15V. Search for "UC384*B" to find other relevant dc to dc converter ics. Total pins of switching converter are 14. Specially, switching converter corresponds to type Switching Regulator or Controllers. The dc to dc regulator can only accept a maximum input voltage of 25V. If you are starting a new project, you should note the dc dc regulator's typical output current is 1A. It is set to 48 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. There is a maximum frequency of 275kHz for this dc regulators.
