LTC3875IUJ#TRPBF Overview

In the 40-WFQFN Exposed Pad package, the switching controller meets most application requirements. It is sufficient to generate 2 outputs with this dc motor controller. An enclosure of Tape & Reel (TR) is used to package the PMIC. With Transistor Driver dc switching's output (s), it is able to handle it. 4.5V~38V is the operating voltage and supply voltage of the dc control. Work well in dc switchers with a -40°C~125°C TJ. The switching controller can be switched at 250kHz~720kHz. dc dc regulators can be carried out with Surface Mount. For efficient switching control, the dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. An analog IC with the DUAL SWITCHING CONTROLLER signal is connected to the switch converters. There are a QUAD terminal on the switching converters. 40 terminations with a variety of function. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. A search for "LTC3875" will reveal other relevant dc to dc converter ics. There are 40 pins on switching converter. It is recommended to use 4.5V as the minimum input voltage of dc dc voltage regulator. At most, the dc to dc regulator accepts 38V input voltage. Hence, OUTPUT VOLTAGE RANGE FROM 0.6 VOLT TO 3.5 VOLT AND 0.6 VOLT TO 5 VOLT is used to better suit the DC to DC voltage regulator's situation.
