UC3846N Overview
It comes in a 16-DIP (0.300, 7.62mm) package, so switching controller can be used for most applications. For 2 outputs, the dc motor controller is appropriate. Packaged in solid enclosures, this pmic has a Tube rating. There are Transistor Driver dc switching's output (s) that it can handle. This dc control operates at 6.95V~40V and has a 6.95V~40V supply voltage. Suitable for a 0°C~70°C TA dc switcher. There is a switch at 500kHz that can be used with this controller. Through Hole makes it suitable for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Frequency Control, Soft Start for efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. switching converters terminal (s) are designed to be at DUAL. 16 terminations with a variety of function. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. 15V nominal DC switcher's voltage input. UC3846 can be used to locate other relevant dc to dc converter ics. There are a total of 16 pins on switching converter. The type is a particular Switching Regulator or Controllers of switching converter. As determined by the test statistics, the output voltage of DC regulator is 13.5V. It's important to remember that the dc dc regulator's normaloutput current is 500mA, 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 50 % on power-up or power-down to ensure reliability. Switching controller operates at 450kHz Hz. DC switching uses 17mA when it is dormant. For nominal working status, the input voltage can be set as 15V. The maximum input voltage of this dc switcher is 40V, so users must limit the voltage accordingly. This voltage controller requires a supply voltage of 15V. An output current greater than 500mA cannot be provided by the dc switcher.
