LTC3890HUH#PBF Overview
It comes in a 32-WFQFN Exposed Pad package, so switching controller can be used for most applications. 2 outputs are supported by the dc motor controller. Packaging for the pmic consists of Tube solid enclosures. With this function, you can deal with Transistor Driver dc switching's outputs (s). DC control operates at 4V~60V volts and has 4V~60V supply voltage. Workable in an dc switcher where -40°C~150°C TJ is the -40°C~150°C TJrm. The switching controller can be switched at 105kHz~835kHz 350kHz~535kHz. The Surface Mount value makes it suitable for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. Thare switching converters has a terminal (s) at QUAD . 32 terminations with various dc switching's functions. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. A search for "LTC3890" will reveal other relevant dc to dc converter ics. Total pins of switching converter are 32. Switching converter type is specifically Switching Regulator or Controllers. This dc dc voltage regulator should be powered by a voltage of 4V. A 5.1V voltage of DC regulator was detected in the test statistics. Voltages 60V are the maximum that the dc to dc regulator will accept. 850kHz is the maximum frequency of this dc regulators. The dc to dc voltage regulator belongs to the PolyPhase? series. Communication with high quality requires 1 channels.
