LTC3858EUFD-1#TRPBF Overview


It comes in the 28-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. It is sufficient to generate 2 outputs with this dc motor controller. The pmic is packaged in Tape & Reel (TR) solid enclosure. The system can process Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 4V~38V. Suitable for working in an dc switcher that has a -40°C~125°C TJ. The switching controller can be switched at 105kHz~835kHz 350kHz~535kHz. The Surface Mount makes it ideal for general dc dc regulator. DCDC regulator is controlled efficiently by Enable, Frequency Control, Power Good, Soft Start. Connected to a DUAL SWITCHING CONTROLLER analog IC, the switch converters are connected to a power supply. The switching converters's terminals (s) are designed at QUAD. 28 terminations with various dc switching's functions. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. Searching "LTC3858" will return other relevant dc to dc converter ics. In total, switching converter has 28 pins. Switching converter is a type of Switching Regulator or Controllers in particular. It is recommended that the dc dc voltage regulator's minimum input voltage be 4V. Statistically, DC regulator outputs 24V volts. The dc to dc regulator can only accept a maximum input voltage of 38V. DC regulators have a maximum frequency of 850kHz. Communication on 1 channels is high-quality.
