8 Terminals 7.6V~30V 8-Pin UC3845 DC to DC converter IC SWITCHING CONTROLLER 500kHz Transistor Driver
UC3845BN Overview
With a 8-DIP (0.300, 7.62mm) package, the switching controller is suitable for a wide range of applications. A solid enclosure of Tube surrounds pmic. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control has a supply voltage and operating voltage of 7.6V~30V. Worked in an dc switcher with a -40°C~150°C TJ rating. Switching can be done at 500kHz with this switching controller. The Through Hole value makes it suitable for general dc dc regulator. For efficient switching control, the dcdc regulator features Frequency Control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. The switching converters's terminals (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. The nominal DC switcher's voltage input is 15V. Search for "UC3845" to find other relevant dc to dc converter ics. There are a total of 8 pins on switching converter. The test statistics indicate that DC regulator outputs a voltage of 5V. You should note that the dc dc regulator's usual output current is 200mA. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. In most applications and prototypes, DC switcher's Through Hole makes it suitable. A frequency of 250kHz is used by the switching controller. Input voltage can be set to 15V for nominal working status. There are 1 phases in this controller. Having a current greater than 17mA may result in improper operation and possibly damage to the component.
