LTC3890EGN-3#PBF Overview
In the 28-SSOP (0.154, 3.90mm Width) package, the switching controller meets most application requirements. dc motor controller is suitable for 2 output generation. Packaged in solid enclosures, this pmic has a Tube rating. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sdc controls with 4V~60V voltage are supplied and operated. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. A switching controller such as this can switch at a value of 105kHz~835kHz 350kHz~535kHz . It is suitable for general dc dc regulator when it is set to Surface Mount. Enable, Frequency Control, Power Good, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. DUAL SWITCHING CONTROLLER analog IC connects the switch converters. switching converters terminal (s) are designed to be at DUAL. A variety of terminations with 28 of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. It is inputted with a DC switcher's voltage of 12V. LTC3890 can be used to locate other relevant dc to dc converter ics. There are 28 pins on switching converter. 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. A maximum voltage of 60V is accepted by the dc to dc regulator as an input voltage. A duty cycle set at 99 % ensures voltage regulator dc to dc reliability during power-on and power-off.
