UC3843BVNG Overview
As a result of 8-DIP (0.300, 7.62mm) compact design, the switching controller is compatible with most applications. It is sufficient to generate 1 outputs with this dc motor controller. PMIC packaging is solid with a Tube enclosure. Transistor Driver dc switching's outputs (s) are supported. dc controls with 7.6V~30V voltage are supplied and operated. Qualified to work in an dc switcher with -40°C~105°C TA. In this switching controller, the switch can be set to Up to 500kHz. The Through Hole value makes it suitable for general dc dc regulator. Switching control is made easier with the dcdc regulator's Frequency Control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. A variety of dc switching's functions can be performed on 8 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. UC384*B can be searched for other relevant dc to dc converter ics. Switching converter has a total of 8 pins. The type is a particular Switching Regulator or Controllers of switching converter. Test statistics indicate DC regulator outputs 5.1V voltage. It's important to remember that the dc dc regulator's normaloutput current is 200mA, so you should note it down when starting a new project. The duty cycle of the voltage regulator dc to dc can be set to 96 % on power-up or power-down to ensure reliability. The Through Hole makes DC switcher suitable for most applications and prototypes. A frequency of 52kHz is set for the switching controller. You can set the input voltage to 30V for nominal working status. There is a possibility that a current higher than 17mA will cause improper operation of the component and possibly damage switching voltage regulators.
