LTC3787HGN#PBF Overview


Capsuled in the 28-SSOP (0.154, 3.90mm Width) package, the switching controller suits most application needs. For outputs of 2, this dc motor controller is suitable. PMIC packaging is solid with a Tube enclosure. Transistor Driver dc switching's outputs (s) are supported. dc control's supply and operating voltages are 4.5V~38V. Suitable for working in an dc switcher that has a -40°C~150°C TJ. The switching controller can be switched at 105kHz~760kHz. dc dc regulator can be generalized using Surface Mount. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start. Connected to a SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. Terminal (s) of the switching converters are designed at the DUAL position. 28 terminations with various dc switching's functions. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. The nominal DC switcher's voltage input is 12V. Searching "LTC3787" will return other relevant dc to dc converter ics. There are a total of 28 pins on switching converter. The minimum input voltage of the dc dc voltage regulator should be 4.5V. It should be fully noted that the dc to dc regulator only accepts 38V input voltage at most. DC regulator's maximum frequency is 850kHz. The value of DC to DC voltage regulator is set at ALSO HAS OUTPUT VOLTAGE UP TO 60V in order to fulfill the requirements more effectively. There are several dc to dc voltage regulator in the PolyPhase? series.
