LTC3869EUFD#PBF Overview


In the 28-WFQFN Exposed Pad package, the switching controller meets most application requirements. For 2 outputs, the dc motor controller is appropriate. Tube is the solid enclosure in which PMIC is packaged. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching's4V~38V is the operating voltage and supply voltage of the dc control. Qualified to work in an dc switcher with -40°C~125°C TJ. Using this switching controller, it is possible to switch at 250kHz~780kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Terminal (s) of the switching converters are designed at the QUAD position. Different dc switching's functions can be applied to 28 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. LTC3869 can be searched for other relevant dc to dc converter ics. There are only 28 pins on switching converter. dc dc voltage regulators should have a minimum input voltage of 4V. Statistically, DC regulator outputs 12.5V volts. Voltages 38V are the maximum that the dc to dc regulator will accept. In most cases, the output current of the dc dc regulator will be 25A, so note that when you start the project. The max frequency of the pmic can reach 850kHz. A high-quality communication requires 1 channels.
