UC3845BDR2G Overview


With its 14-SOIC (0.154, 3.90mm Width) package, the switching controller fits the needs of 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. 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 0°C~70°C TA rating. With this switching controller, you can switch at 500kHz. The Surface Mount allows it to be used for dc dc regulator in general. The dcdc regulator features Frequency Control for efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a terminal (s) on the switching converters that are designed at DUAL. A variety of terminations with 14 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. You can find other relevant dc to dc converter ics by searching "UC384*B". Pins number 14 of switching converter in total. There is a particular type of Switching Regulator or Controllers in switching converter. A 5V voltage of DC regulator was detected in the test statistics. If you are starting a new project, you should note the dc dc regulator's typical output current is 1A. To ensure the reliability under power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set as 48 %. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. Switching controllers work at 52kHz Hz. Components may be damaged if their current is greater than 17mA.
