LTC3787MPGN Product Details
LTC3787MPGN Overview
As a result of 28-SSOP (0.154, 3.90mm Width) compact design, the switching controller is compatible with most applications. 2 outputs can be generated with the dc motor controller. There is a Tube solid enclosure around the pmic. The program can handle Transistor Driver dc switching's outputs (s). 4.5V~38V is the operating voltage and supply voltage of the dc control. Qualified to work in a -55°C~150°C TJ dc switcher. In this switching controller, the switch can be set to 105kHz~760kHz. A generalization of dc dc regulator can be made using Surface Mount. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Power Good, Soft Start. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. Terminal (s) of the switching converters are designed at the DUAL position. Different dc switching's functions can be applied to 28 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. There is a DC switcher's nominal voltage of 12V. Search for "LTC3787" to find other relevant dc to dc converter ics. dc dc voltage regulators should have a minimum input voltage of 4.5V. At most, the dc to dc regulator accepts 38V input voltage. The value of DC to DC voltage regulator is set to ALSO HAS OUTPUT VOLTAGE UP TO 60V in order to better satisfy the requirement. Thare are switch converters of the PolyPhase? series.
