LTC3890HGN-1#PBF Product Details
LTC3890HGN-1#PBF Overview
This switching controller fits most application requirements since it is packaged in a 28-SSOP (0.154, 3.90mm Width) package. There is enough capacity in the dc motor controller to generate the output for the 2 input. An enclosure of Tube is used to package the PMIC. The system can process Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 4V~60V. Suitable for a -40°C~150°C TJ dc switcher. With this switching controller, you can switch at 105kHz~835kHz 350kHz~535kHz. It is suitable for general dc dc regulator when it is set to Surface Mount. To ensure efficient switching, this dcdc regulator features a Enable, Frequency Control, Power Good, Soft Start, Tracking. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. The switching converters's terminal (s) are designed at DUAL . Various 28 terminations. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 12V is input. You can find other relevant dc to dc converter ics by searching "LTC3890". 28 pins are present on switching converter. 4V should be the minimum input voltage for the dc dc voltage regulator. Considering the dc to dc regulator can only accept 60V input voltage, it is important to take note of this. It is estimated that this dc regulatorhas a maximum frequency of 850kHz. Communication on 1 channels is high-quality.
