LTC3875EUJ#TRPBF Overview

With a 40-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 2 input. A solid enclosure of Tape & Reel (TR) surrounds pmic. Transistor Driver dc switching's outputs (s) are supported. DC control operates at 4.5V~38V volts and has 4.5V~38V supply voltage. Qualified to work in an dc switcher with -40°C~125°C TJ. This switching controller can switch at 250kHz~720kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. Thare switch converters are connected to an analog integrated circuit (IC) of type DUAL SWITCHING CONTROLLER. Terminal (s) of the switching converters are designed at the QUAD position. A variety of dc switching's functions can be performed on 40 terminations. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input of 15V. LTC3875 can be searched for other relevant dc to dc converter ics. Input voltage of dc dc voltage regulator should be 4.5V. Voltages 38V are the maximum that the dc to dc regulator will accept. DC to DC voltage regulator has the value of OUTPUT VOLTAGE RANGE FROM 0.6 VOLT TO 3.5 VOLT AND 0.6 VOLT TO 5 VOLT to better satisfy the requirement.
