8 Terminals 7.6V~30V 8-Pin UC3843 DC to DC converter IC SWITCHING CONTROLLER 1 Outputs Up to 500kHz Transistor Driver
UC3843BN Overview
With its 8-DIP (0.300, 7.62mm) package, the switching controller fits the needs of most applications. For outputs of 1, this dc motor controller is suitable. Tube solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 7.6V~30V and has a 7.6V~30V supply voltage. Worked in a 0°C~70°C TJ dc switcher before. In this switching controller, the switch can be set to Up to 500kHz. The Through Hole allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Frequency Control. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position DUAL . The 8 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 15V is input. Searching "UC3843" will return other relevant dc to dc converter ics. 8 pins are on switching converter. Based on the test statistics, DC regulator outputs voltage 5.05V. If you are starting a new project, you should note the dc dc regulator's typical output current is 200mA. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 100 %. In most applications and prototype designs, DC switcher is qualified as a Through Hole. Switching controllers work at 250kHz Hz. A nominal working status is achieved when the input voltage is set to 15V. There is a possibility of damage to the component if the switching voltage regulators current exceeds 17mA.
