LTC3853IUJ#TRPBF Overview


With a 40-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. The dc motor controller is adquate to generate for 3 outputs. An enclosure of Tape & Reel (TR) is used to package the PMIC. Transistor Driver dc switching's outputs (s) can be handled by it. Voltages 4.5V~24V are the dc control's supply voltage and operating voltage, respectively. Work well in dc switchers with a -40°C~125°C TJ. With this switching controller, you can switch at 250kHz~750kHz. The Surface Mount allows it to be used for dc dc regulator in general. To provide efficient switching control, Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. switching converters terminal (s) are designed to be at QUAD. A variety of terminations with 40 of dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. In addition to "LTC3853", there are other relevant dc to dc converter ics you can find. There are a total of 40 pins on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. The minimum input voltage of the dc dc voltage regulator should be 4.5V. DC regulator outputs 13.5V voltage based on test statistics. The dc to dc regulator can only accept 24V input voltage. There is a maximum frequency of 830kHz for this dc regulators. A high-quality communication requires 1 channels.
