LTC3809IDD-1#PBF Overview
This switching controller fits most application requirements since it is packaged in a 10-WFDFN Exposed Pad package. There is sufficient capacity to generate switching controller for outputs 1. Tube solid enclosure protects the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). This dc control has a supply voltage and operating voltage of 2.75V~9.8V. Qualified to work in an dc switcher with -40°C~85°C TA. The switching controller can be switched at 550kHz. Surface Mount makes it suitable for general dc dc regulator. Enable, Soft Start, Tracking is used for efficient switching control in the dcdc regulator. The switch converters are connected to a SWITCHING CONTROLLER analog IC. The switching converters's terminal (s) are designed at QUAD . A variety of terminations with 10 of dc switching. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. The nominal DC switcher's voltage input is 4.2V. A search for "LTC3809" will reveal other relevant dc to dc converter ics. In total, switching converter has 10 pins. Switching converter type is specifically Switching Regulator or Controllers. It is recommended that the dc dc voltage regulator's minimum input voltage be 2.75V. DC regulator outputs 9.8V voltage according to the test statistics. A starting point for a project is to note down the dc dc regulator's usual output current, which is 5A. It is estimated that this dc regulatorhas a maximum frequency of 600kHz.
