LTC3890HGN-1#TRPBF Product Details
LTC3890HGN-1#TRPBF Overview
The switching controller fits in the 28-SSOP (0.154, 3.90mm Width) package and is ideal for most applications. 2 outputs are supported by the dc motor controller. PMIC packaging is solid with a Tape & Reel (TR) enclosure. Transistor Driver dc switching's outputs (s) are supported. 4V~60V is the supply voltage and the operating voltage of the dc control. Worked in a -40°C~150°C TJ dc switcher before. In this switching controller, the switch can be set to 105kHz~835kHz 350kHz~535kHz. As it has a Surface Mount value, it can be used for general dc dc regulator. To ensure efficient switching, this dcdc regulator features a Enable, Frequency Control, Power Good, Soft Start, Tracking. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. DUAL are the position of the terminal of the switching converters. An array of 28 terminations of dc switching. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. In addition to "LTC3890", there are other relevant dc to dc converter ics you can find. There are a total of 28 pins on switching converter. 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 is limited to 60V input voltage. 850kHz is the maximum frequency of this dc regulators. Communication with high quality requires 1 channels.
