UC3844BN Overview
It comes in a 8-DIP (0.300, 7.62mm) package, so switching controller can be used for most applications. There is sufficient capacity to generate switching controller for outputs 1. PMIC packaging is solid with a Tube enclosure. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control has a supply voltage and operating voltage of 10V~30V. Worked in an dc switcher with a 0°C~70°C TJ rating. With this switching controller, you can switch at Up to 500kHz. It is suitable for general dc dc regulator when it is set to Through Hole. Switching control is made easier with the dcdc regulator's Frequency Control. SWITCHING CONTROLLER analog IC connects the switch converters. DUAL are the position of the terminal of the switching converters. 8 terminations with a variety of function. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's input voltageis 15V volts. You can find other relevant dc to dc converter ics by searching "UC3844". In total, switching converter has 8 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. Statistically, DC regulator outputs 13.5V volts. 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. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 50 %. In most applications and prototypes, DC switcher's Through Hole makes it suitable. The switching controller works at a frequency of 250kHz. A nominal working status is achieved when the input voltage is set to 15V. In this case, the dc switcher won't produce more than 1A watts of output current. Having a current greater than 17mA may result in improper operation and possibly damage to the component.
