LTC3874EUF-1#TRPBF Product Details
LTC3874EUF-1#TRPBF Overview
In the 24-WFQFN Exposed Pad package, the switching controller meets most application requirements. dc motor controller is suitable for 2 output generation. PMIC is packaged in a solid enclosure of Tape & Reel (TR). With this function, you can deal with Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4.5V~38V. Qualified to work in a -40°C~125°C TJ dc switcher. There is a switch at 250kHz~1MHz that can be used with this controller. The Surface Mount makes it ideal for general dc dc regulator. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control. The switch converters are connected to a SWITCHING CONTROLLER analog IC. The switching converters's terminal (s) are designed at QUAD . 24 terminations with a variety of function. The control methods that these dc dc converter ics use include PHASE-SHIFT CONTROL. 12V nominal DC switcher's voltage input. You can find other relevant dc to dc converter ics by searching "LTC3874". The switching converter has a total of 24 pins. The minimum input voltage of the dc dc voltage regulator should be 4.5V. It should be fully noted that the dc to dc regulator only accepts 38V input voltage at most. There are several dc to dc voltage regulator in the PolyPhase? series. At 5.5V, the dc controller's highest voltage output is tested.
