LTC3890MPUH#PBF Product Details
LTC3890MPUH#PBF Overview
This switching controller fits most application requirements since it is packaged in a 32-WFQFN Exposed Pad package. 2 outputs are supported by the dc motor controller. PMIC packaging is solid with a Tube enclosure. The system can process Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 4V~60V. Worked in an dc switcher with a -55°C~150°C TJ rating. This switching controller can switch at 105kHz~835kHz 350kHz~535kHz. dc dc regulator is made easier with Surface Mount. Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. Switch converters are connected to ICs with DUAL SWITCHING CONTROLLER analog outputs. There are a terminal (s) on the switching converters that are designed 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. The DC switcher's nominal voltage is 12V. A search for "LTC3890" will reveal other relevant dc to dc converter ics. There are only 32 pins on switching converter. Switching converter type is specifically Switching Regulator or Controllers. 4V should be the minimum input voltage for the dc dc voltage regulator. A 24V voltage of DC regulator was detected in the test statistics. The dc to dc regulator is limited to 60V input voltage. There is a maximum frequency of 850kHz on this dc regulators. PolyPhase? series dc to dc voltage regulator belong to this series. It is recommended that there be 1 channels for high-quality communication.
