LTC3890EUH#TRPBF Product Details

LTC3890EUH#TRPBF Overview


The switching controller fits in the 32-WFQFN Exposed Pad package and is ideal for most applications. For 2 outputs, the dc motor controller is appropriate. The pmic is packaged in Tape & Reel (TR) solid enclosure. Transistor Driver dc switching's outputs (s) are supported. 4V~60V is the operating voltage and supply voltage of the dc control. Worked in an dc switcher with a -40°C~125°C TJ rating. Switching can be done at 105kHz~835kHz 350kHz~535kHz with this switching controller. As it has a Surface Mount value, it can be used for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Frequency Control, Phase Control, Power Good, Soft Start, Tracking for efficient switching control. A DUAL SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Terminal (s) of the switching converters are designed at the QUAD position. Various 32 terminations. These dc dc converter ics adapt several control methods, including PULSE WIDTH MODULATION. DC switcher's input voltageis 12V volts. LTC3890 can be used to locate other relevant dc to dc converter ics. In total, switching converter has 32 pins. Switching converter is a type of Switching Regulator or Controllers in particular. It is recommended to use 4V as the minimum input voltage of dc dc voltage regulator. The test statistics indicate that DC regulator outputs a voltage of 24V. The dc to dc regulator can only accept 60V input voltage. There is a maximum frequency of 850kHz for this dc regulators. It belongs to the PolyPhase? series of dc to dc voltage regulator. Channels 1 are required for high-quality communication.
