LTC3891IUDC#TRPBF Product Details

LTC3891IUDC#TRPBF Overview


With its 20-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. For outputs of 1, this dc motor controller is suitable. Tape & Reel (TR) solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control operates at 4V~60V and has a 4V~60V supply voltage. Worked in a -40°C~125°C TJ dc switcher before. In this switching controller, the switch can be set to 105kHz~835kHz 350kHz~535kHz. The Surface Mount allows it to be used for dc dc regulator in general. In order to control switching efficiently, the dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. SWITCHING CONTROLLER analog IC connects the switch converters. Switching converters are designed with the terminal (s) at position QUAD . The 20 terminations can be used for a wide range of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. Searching "LTC3891" will return other relevant dc to dc converter ics. There is a particular type of Switching Regulator or Controllers in switching converter. Input voltage of dc dc voltage regulator should be 4V. Based on the test statistics, DC regulator outputs voltage 5.1V. It should be noted that the dc to dc regulator only accepts 60V voltage as input voltage. This value is ALSO OPERATES IN ADJUSTABLE MODE FROM 0.80V TO 24V so that DC to DC voltage regulator better serves the purpose.
