LTC3787HUFD#TRPBF Overview
This switching controller fits most application requirements since it is packaged in a 28-WFQFN Exposed Pad package. The dc motor controller is adquate to generate for 2 outputs. There is a Tape & Reel (TR) solid enclosure around the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. 4.5V~38V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where -40°C~150°C TJ is the -40°C~150°C TJrm. There is a switch at 105kHz~760kHz that can be used with this controller. Surface Mount makes it suitable for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Current Limit, Enable, Frequency Control, Power Good, Soft Start. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. The switching converters's terminal (s) are designed at DUAL . A variety of 28 terminations are available in dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. It is inputted with a DC switcher's voltage of 12V. A search for "LTC3787" will reveal other relevant dc to dc converter ics. 4.5V should be the minimum input voltage for the dc dc voltage regulator. It should be fully noted that the dc to dc regulator only accepts 38V input voltage at most. This value is ALSO HAS OUTPUT VOLTAGE UP TO 60V so that DC to DC voltage regulator better serves the purpose. The dc to dc voltage regulator is from the PolyPhase? series.
