LTC3855IFE#PBF Product Details

LTC3855IFE#PBF Overview


In the 38-TFSOP (0.173, 4.40mm Width) Exposed Pad package, the switching controller meets most application requirements. There is sufficient capacity to generate switching controller for outputs 2. There is a Tube solid enclosure around the pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 4.5V~38V volts and has 4.5V~38V supply voltage. Suitable for working in an dc switcher that has a -40°C~125°C TJ. It can switch at 250kHz~770kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. To provide efficient switching control, Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking is included in the dcdc regulator. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. DUAL are the position of the terminal of the switching converters. Various 38 terminations. This dc dc converter ic uses a variety of control techniques, including PHASE-SHIFT CONTROL. There is a DC switcher's nominal voltage of 15V. In addition to "LTC3855", there are other relevant dc to dc converter ics you can find. There are 38 pins on switching converter. Specifically, switching converter falls under the Switching Regulator or Controllers category. It is recommended that the dc dc voltage regulator's minimum input voltage be 4.5V. DC regulator850kHz has the maximum frequency. The dc to dc voltage regulator is from the PolyPhase® series. Communication on 1 channels is high-quality.
