LTC3787HUFD#PBF Overview

Capsuled in the 28-WFQFN Exposed Pad package, the switching controller suits most application needs. 2 outputs are supported by the dc motor controller. Packaged in solid enclosures, this pmic has a Tube rating. Transistor Driver dc switching's outputs (s) are supported. This dc control operates at 4.5V~38V and has a 4.5V~38V supply voltage. Suitable for working in an dc switcher that has a -40°C~150°C TJ. There is a switch at 105kHz~760kHz that can be used with this controller. dc dc regulator can be generalized using Surface Mount. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Power Good, Soft Start. A SWITCHING CONTROLLER analog IC is connected to the switch converters. Terminal (s) of the switching converters are designed at the QUAD position. Different dc switching's functions can be applied to 28 terminations. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. You can find other relevant dc to dc converter ics by searching "LTC3787". There are 28 pins on switching converter. dc dc voltage regulators should have a minimum input voltage of 4.5V. The dc to dc regulator can only accept 38V input voltage. DC regulator has a maximum frequency of 850kHz. This value is ALSO HAS OUTPUT VOLTAGE UP TO 60V so that DC to DC voltage regulator better serves the purpose. Thare are switch converters of the PolyPhase? series.
