LTC3890MPGN-1#PBF Overview

With a 28-SSOP (0.154, 3.90mm Width) package, the switching controller is suitable for a wide range of applications. There is sufficient capacity to generate switching controller for outputs 2. PMIC is packaged in a solid enclosure of Tube. There are Transistor Driver dc switching's output (s) that it can handle. DC control operates at 4V~60V volts and has 4V~60V supply voltage. Suitable for work in a -55°C~150°C TJ dc switcher. A switching controller such as this can switch at a value of 105kHz~835kHz 350kHz~535kHz . A generalization of dc dc regulator can be made using Surface Mount. Enable, Frequency Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog IC is connected to the switch converters. There are a DUAL terminal on the switching converters. A variety of terminations with 28 of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 12V. A search for "LTC3890" will reveal other relevant dc to dc converter ics. Total pins of switching converter are 28. Input voltage of dc dc voltage regulator must be 4V. Statistically, DC regulator outputs 24V volts. Considering the dc to dc regulator can only accept 60V input voltage, it is important to take note of this. DC regulator has a maximum frequency of 850kHz. Channels are 1 for high-quality communication.
