LTC3857EGN-1#PBF Overview
It comes in a 28-SSOP (0.154, 3.90mm Width) package, so switching controller can be used for most applications. For outputs of 2, this dc motor controller is suitable. Packaged in solid enclosures, this pmic has a Tube rating. The system can process Transistor Driver dc switching's outputs (s). DC control operates at 4V~38V volts and has 4V~38V supply voltage. Worked in an dc switcher with a -40°C~125°C TJ rating. In this switching controller, the switch can be set to 105kHz~835kHz 350kHz~535kHz. dc dc regulator can be generalized using Surface Mount. The dcdc regulator features Enable, Frequency Control, Power Good, Soft Start, Tracking for efficient switching control. A DUAL SWITCHING CONTROLLER analog IC is connected to the switch converters. Thare switching converters has a terminal (s) at DUAL . The 28 terminations can be used for a wide range 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 12V. Search for "LTC3857" to find other relevant dc to dc converter ics. Pins number 28 of switching converter in total. Switching converter type is specifically Switching Regulator or Controllers. 4V should be the minimum input voltage for the dc dc voltage regulator. DC regulator outputs 24V voltage based on test statistics. It should be fully noted that the dc to dc regulator only accepts 38V input voltage at most. 850kHz is the maximum frequency of this dc regulators. Basically, it's a dc to dc voltage regulator from the PolyPhase? series. For high-quality communication, there are 1 channels.
