LTC3890IUH#PBF Overview

Capsuled in the 32-WFQFN Exposed Pad package, the switching controller suits most application needs. There is enough capacity in the dc motor controller to generate the output for the 2 input. Tube is the solid enclosure in which PMIC is packaged. Transistor Driver dc switching's outputs (s) are supported. 4V~60V is the supply voltage and the operating voltage of the dc control. Suitable for working in an dc switcher that has a -40°C~125°C TJ. With this switching controller, you can switch at 105kHz~835kHz 350kHz~535kHz. dc dc regulator can be generalized using Surface Mount. Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. The switching converters's terminals (s) are designed at QUAD. Different dc switching's functions can be applied to 32 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 12V. LTC3890 can be searched for other relevant dc to dc converter ics. In total, switching converter has 32 pins. The type is a particular Switching Regulator or Controllers of switching converter. It is recommended that the input voltage of the dc dc voltage regulator be 4V. DC regulator outputs 24V voltage according to the test statistics. It should be fully noted that the dc to dc regulator only accepts 60V input voltage at most. There is a maximum frequency of 850kHz for this dc regulators. A dc to dc voltage regulator in the PolyPhase? series, it belongs to this family. Communication with high quality requires 1 channels.
