LTC3890HUH#TRPBF Overview


With its 32-WFQFN Exposed Pad package, the switching controller fits the needs of most applications. For 2 outputs, the dc motor controller is appropriate. Tape & Reel (TR) solid enclosure protects the pmic. Transistor Driver dc switching's outputs (s) can be handled by it. This dc control operates at 4V~60V and has a 4V~60V supply voltage. Worked in an dc switcher with a -40°C~150°C TJ rating. Switching can be done at 105kHz~835kHz 350kHz~535kHz with this switching controller. The Surface Mount allows it to be used for dc dc regulator in general. 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. The switching converters's terminal (s) are designed at QUAD . A variety of 32 terminations are available in dc switching. PULSE WIDTH MODULATION is an example of one of the control techniques these dc dc converter ics adapt. A DC switcher's nominal voltage of 12V is input. LTC3890 can be searched for other relevant dc to dc converter ics. 32 pins are on switching converter. Specially, switching converter corresponds to type Switching Regulator or Controllers. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. Based on the test statistics, DC regulator outputs voltage 24V. The dc to dc regulator can only accept a maximum input voltage of 60V. This dc regulatorhas a max frequency of 850kHz. PolyPhase? series dc to dc voltage regulator belong to this series. Channels are 1 for high-quality communication.
