UC3845ADM-TR Product Details

UC3845ADM-TR Overview


Capsuled in the 8-SOIC (0.154, 3.90mm Width) package, the switching controller can be used for a wide range of applications. For outputs of 1, this dc motor controller is suitable. PMIC packaging is solid with a Tape & Reel (TR) enclosure. Transistor Driver dc switching's outputs (s) are supported. dc controls with 7.6V~30V voltage are supplied and operated. Suitable for work in a 0°C~70°C TA dc switcher. Switching can be done at 500kHz with this switching controller. The Surface Mount allows it to be used for dc dc regulator in general. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminals (s) are designed at DUAL. A variety of terminations with 8 of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 15V. UC3845 can be used to locate other relevant dc to dc converter ics. Total pins of switching converter are 8. Switching converter type is specifically Switching Regulator or Controllers. The dc to dc regulator is limited to 30V input voltage. It is set to 96 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. Switching converter outputs current to the greatest value of 1A.
