L6997S Overview
Capsuled in the 20-TSSOP (0.173, 4.40mm Width) package, the switching controller can be used for a wide range of applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. An enclosure of Tube is used to package the PMIC. There are Transistor Driver dc switching's output (s) that it can handle. dc control's supply and operating voltages are 3V~5.5V. Worked in a -40°C~125°C TJ dc switcher before. As it has a Surface Mount value, it can be used for general dc dc regulator. Current Limit, Enable, Phase Control, Power Good, Soft Start provides dcdc regulator efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . A variety of 20 terminations are available in dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. A DC switcher's nominal voltage of 3.3V is input. L6997 can be searched for other relevant dc to dc converter ics. 20 pins are on switching converter. Particularly, switching converter is a type of Switching Regulator or Controllers. Statistically, DC regulator outputs 12V volts. You should note that the dc dc regulator's usual output current is 30A. This Surface Mount makes DC switcher suitable for most prototypes and applications. There is a maximum frequency of 1MHz for this dc regulators. When running the voltage regulator dc to dc in a circuit, users should apply 35V to ensure safety and reliability. In order to limit the voltage of a dc switcher whose maximum input voltage is 35V, it must be limited by the user. Voltage 1V must be supplied. Input current cannot exceed 20A with this dc switcher. Depending on the datasheet, the switching converter can output 606mV volts at its peak.
