LTC3856IUH#PBF Overview

It comes in a 32-WFQFN Exposed Pad package, so switching controller can be used for most applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. Packaging for the pmic consists of Tube solid enclosures. Transistor Driver dc switching's outputs (s) are supported. The supply and operating voltage of the dc control are 4.5V~38V. Worked in an dc switcher with a -40°C~125°C TJ rating. It can switch at 250kHz~770kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. SWITCHING CONTROLLER analog IC connects the switch converters. The switching converters's terminal (s) are designed at QUAD . 38 terminations with a variety of function. DC switcher's voltage input is 15V. Other relevant dc to dc converter ics will be returned if you search "LTC3856". Pins number 32 of switching converter in total. Specially, switching converter corresponds to type Switching Regulator or Controllers. Statistically, DC regulator outputs 5V volts. Voltages 38V are the maximum that the dc to dc regulator will accept. It's important to remember that the dc dc regulator's normaloutput current is 25A, so you should note it down when starting a new project. There is a maximum frequency of 850kHz for this dc regulators. To better satisfy the need, DC to DC voltage regulator has a value of ALSO OPERATES AS LDO REGULATOR, OPERATES IN ADJUSTABLE MODE FROM 0.6 TO 5V. The dc to dc voltage regulator is from the PolyPhase? series. A high-quality communication requires 1 channels.
