LTC3857EGN-1#TRPBF Product Details

LTC3857EGN-1#TRPBF Overview


It comes in the 28-SSOP (0.154, 3.90mm Width) package, which makes switching controller suitable for most applications. It is sufficient to generate 2 outputs with this dc motor controller. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 4V~38V. Qualified to work in an dc switcher with -40°C~125°C TJ. The switching controller can be switched at 105kHz~835kHz 350kHz~535kHz. dc dc regulators can be carried out with Surface Mount. Enable, Frequency Control, Power Good, Soft Start, Tracking provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. Different dc switching's functions can be applied to 28 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. LTC3857 can be searched for other relevant dc to dc converter ics. In total, switching converter has 28 pins. Switching converter type is specifically Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4V. Statistically, DC regulator outputs 24V volts. This dc to dc regulator accepts only 38V input voltage at most. 850kHz is the maximum frequency of this dc regulators. A dc to dc voltage regulator in the PolyPhase® series, it belongs to this family. In order to ensure high-quality communication, there are 1 channels available.
