UC3843BD1R2G Overview


It comes in the 8-SOIC (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. This dc motor controller can be used to generate outputs with 1 numbers. Packaged in solid enclosures, this pmic has a Tape & Reel (TR) rating. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 7.6V~30V. A 0°C~70°C TA dc switcher is not a problem. The switching controller is capable of switching at the Up to 500kHz position. It is suitable for general dc dc regulator when it is set to Surface Mount. Frequency Control provides dcdc regulator efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. switching converters terminal (s) are designed to be at DUAL. An array of 8 terminations of dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. DC switcher's input voltageis set to 15V. You can find other relevant dc to dc converter ics by searching "UC384*B". In total, switching converter has 8 pins. Switching converter is a special type of Switching Regulator or Controllers. A 5.1V voltage of DC regulator was detected in the test statistics. It should be noted that the dc to dc regulator only accepts 25V voltage as input voltage. In most cases, the output current of the dc dc regulator will be 1A, so note that when you start the project. It is set to 96 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sThere is 52kHz frequency setting on the switching controller. There is a possibility that a current higher than 17mA will cause improper operation of the component and possibly damage switching voltage regulators.
