LTC3858EUH#TRPBF Overview
This switching controller fits most application requirements since it is packaged in a 32-WFQFN Exposed Pad package. 2 outputs can be generated with the dc motor controller. PMIC packaging is solid with a Tape & Reel (TR) enclosure. There are Transistor Driver dc switching's output (s) that it can handle. A 4V~38V voltage is supplied to the dc control and used for operating it. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. This switching controller can switch at 105kHz~835kHz 350kHz~535kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Frequency Control, Power Good, Soft Start. An analog IC DUAL SWITCHING CONTROLLER is connected to the switch converters. There are a terminal (s) on the switching converters that are designed at QUAD. Different dc switching's functions can be applied to 32 terminations. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 12V. You can find other relevant dc to dc converter ics by searching "LTC3858". 32 pins are on switching converter. Switching converter type is specifically Switching Regulator or Controllers. Input voltage of dc dc voltage regulator must be 4V. Statistically, the DC regulator outputs 24V voltage. At most, the dc to dc regulator accepts 38V input voltage. This dc regulatorhas a max frequency of 850kHz. The dc to dc voltage regulator is from the PolyPhase? series. Channels 1 are required for high-quality communication.
