LTC3855IUJ#TRPBF Overview

Capsuled in the 40-WFQFN Exposed Pad package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 2 outputs. PMIC is packaged in a solid enclosure of Tape & Reel (TR). The program can handle Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4.5V~38V. Suitable for working in an dc switcher that has a -40°C~125°C TJ. There is a switch at 250kHz~770kHz that can be used with this controller. dc dc regulator is made easier with Surface Mount. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. An analog IC DUAL SWITCHING CONTROLLER is connected to the switch converters. The switching converters's terminal (s) are designed at DUAL . An array of 40 terminations of dc switching. A few of the control techniques these dc dc converter ics adapt include PHASE-SHIFT CONTROL. DC switcher's input voltageis 15V volts. In addition to "LTC3855", there are other relevant dc to dc converter ics you can find. Total pins of switching converter are 40. In particular, switching converter belongs to the Switching Regulator or Controllers family. An input voltage of 4.5V is the minimum required for the dc dc voltage regulator. Test statistics indicate DC regulator outputs 12.5V voltage. It should be noted that the dc to dc regulator only accepts 38V voltage as input voltage. DC regulator850kHz has the maximum frequency. It belongs to the dc to dc voltage regulator series PolyPhase?. There are 1 channels for high-quality communication.
