LTC3890IUH-2#TRPBF Product Details
LTC3890IUH-2#TRPBF Overview
As a result of 32-WFQFN Exposed Pad compact design, the switching controller is compatible with most applications. 2 outputs are supported by the dc motor controller. An enclosure of Tape & Reel (TR) is used to package the PMIC. The system can process Transistor Driver dc switching's outputs (s). 4V~60V is the supply voltage and the operating voltage of the dc control. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. The switching controller is capable of switching at the 105kHz~835kHz 350kHz~535kHz position. dc dc regulator can be generalized using Surface Mount. Switching control is made easier with the dcdc regulator's Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. switching converters terminal (s) are designed to be at QUAD. There are many different types of terminations for 32. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 12V. A search for "LTC3890" will reveal other relevant dc to dc converter ics. The type is a particular Switching Regulator or Controllers of switching converter. Input voltage of dc dc voltage regulator must be 4V. Voltages 60V are the maximum that the dc to dc regulator will accept. There are several dc to dc voltage regulator in the PolyPhase® series.
