LTC3890MPUH-2#TRPBF Overview
With a 32-WFQFN Exposed Pad package, the switching controller is suitable for a wide range of applications. The dc motor controller is adquate to generate for 2 outputs. Tape & Reel (TR) solid enclosure protects the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. This dc control operates at 4V~60V and has a 4V~60V supply voltage. Suitable for working in an dc switcher that has a -55°C~150°C TJ. The switching controller is capable of switching at the 105kHz~835kHz 350kHz~535kHz position. A generalization of dc dc regulator can be made using Surface Mount. The dcdc regulator features Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking for efficient switching control. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. There are a QUAD terminal on the switching converters. A variety of dc switching's functions can be performed on 32 terminations. It includes PULSE WIDTH MODULATION as one of the control techniques dc dc converter ic adapts. DC switcher's input voltageis set to 12V. In addition to "LTC3890", there are other relevant dc to dc converter ics you can find. Switching converter is a type of Switching Regulator or Controllers in particular. It is recommended that the input voltage of the dc dc voltage regulator be 4V. Considering the dc to dc regulator can only accept 60V input voltage, it is important to take note of this. Basically, it's a dc to dc voltage regulator from the PolyPhase? series.
