UC3845BN Overview
As a result of 8-DIP (0.300, 7.62mm) compact design, the switching controller is compatible with most applications. PMIC is packaged in a solid enclosure of Tube. Transistor Driver dc switching's outputs (s) can be handled by it. A 7.6V~30V voltage is supplied to the dc control and used for operating it. Worked in an dc switcher with a -40°C~150°C TJ rating. There is a switch at 500kHz that can be used with this controller. The Through Hole value makes it suitable for general dc dc regulator. Frequency Control provides dcdc regulator efficient switching control. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminal (s) are designed at DUAL . An array of 8 terminations of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. Searching "UC3845" will return other relevant dc to dc converter ics. Pins number 8 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. Test statistics indicate DC regulator outputs 5V voltage. A starting point for a project is to note down the dc dc regulator's usual output current, which is 200mA. As a result of this, the maximum duty cycle of the voltage regulator dc to dc must remain 50 % during power-up and power-down. DC switcher's Through Hole makes it qualified for most application and prototype designs. DC switcher'sA frequency of 250kHz is used by the switching controller. You can set the input voltage to 15V for nominal working status. There are 1 phases in this controller. In the presence of a current greater than 17mA, the component may fail to operate properly and may be damaged.
