LTC3891MPUDC#PBF Product Details

LTC3891MPUDC#PBF Overview


It comes in a 20-WFQFN Exposed Pad package, so switching controller can be used for most applications. This dc motor controller can be used to generate outputs with 1 numbers. Tube is the solid enclosure in which PMIC is packaged. With Transistor Driver dc switching's output (s), it is able to handle it. dc controls with 4V~60V voltage are supplied and operated. A -55°C~150°C TJ dc switcher is not a problem. A switching controller such as this can switch at a value of 105kHz~835kHz 350kHz~535kHz . It is suitable for general dc dc regulator when it is set to Surface Mount. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Power Good, Soft Start, Tracking. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at QUAD . A variety of 20 terminations are available in dc switching. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. LTC3891 can be used to locate other relevant dc to dc converter ics. The switching converter has a total of 20 pins. Switching converter is a special type of Switching Regulator or Controllers. 4V should be the minimum input voltage for the dc dc voltage regulator. As determined by the test statistics, the output voltage of DC regulator is 24V. The dc to dc regulator is limited to 60V input voltage. You should note down the dc dc regulator's usual output current of 5A when you start a project. This dc regulatorhas a max frequency of 835kHz. As a result, DC to DC voltage regulator has a value of ALSO OPERATES IN ADJUSTABLE MODE FROM 0.80V TO 24V so that the need can be met more directly.
