L6997STR Overview
As a result of 20-TSSOP (0.173, 4.40mm Width) compact design, the switching controller is compatible with most applications. For 1 outputs, the dc motor controller is appropriate. A solid enclosure of Tape & Reel (TR) surrounds pmic. With this function, you can deal with Transistor Driver dc switching's outputs (s). 3V~5.5V is the operating voltage and supply voltage of the dc control. Workable in an dc switcher where -40°C~125°C TJ is the -40°C~125°C TJrm. dc dc regulator can be generalized using Surface Mount. The dcdc regulator features Current Limit, Enable, Phase Control, Power Good, Soft Start for efficient switching control. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Terminal (s) of the switching converters are designed at the DUAL position. There are many different types of terminations for 20. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 3.3V. L6997 can be used to locate other relevant dc to dc converter ics. The switching converter has a total of 20 pins. In particular, switching converter is a type of Switching Regulator or Controllers. Input voltage of dc dc voltage regulator should be 3V. DC regulator outputs 12V voltage based on test statistics. This dc to dc regulator accepts only 5.5V input voltage at most. If you are starting a new project, you should note the dc dc regulator's typical output current is 30A. In most applications and prototypes, DC switcher's Surface Mount makes it suitable. There is a maximum frequency of 1MHz on this dc regulators. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 35V. When the dc switching is dormant, it uses 600μA.
