UC3843ADX Overview

With its 8-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of most applications. For 1 outputs, the dc motor controller is appropriate. The pmic is packaged in Tape & Reel (TR) solid enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. DC control operates at 7.6V~30V volts and has 7.6V~30V supply voltage. Work well in dc switchers with a 0°C~70°C TA. It can switch at Up to 500kHz. A generalization of dc dc regulator can be made using Surface Mount. Frequency Control is used for efficient switching control in the dcdc regulator. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Thare switching converters has a terminal (s) at DUAL . 8 terminations with a variety of function. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 15V. Other relevant dc to dc converter ics will be returned if you search "UC3843". The switching converter has a total of 8 pins. At most, the dc to dc regulator accepts 25V input voltage. You should note down the dc dc regulator's usual output current of 1kA when you start a project. The duty cycle of the voltage regulator dc to dc can be set to 100 % on power-up or power-down to ensure reliability. DC switcher's Surface Mount qualifies it for most applications and prototypes. DC regulator's maximum frequency is 500kHz. It runs on a supply current of 17mA. This the controllers dc receives a 17mA nominal current supply.
