LM2647LQX Product Details

LM2647LQX Overview


Capsuled in the 28-WFQFN Exposed Pad package, the switching controller suits most application needs. The dc motor controller is adquate to generate for 2 outputs. The pmic is packaged in Tape & Reel (TR) solid enclosure. It is capable of dealing with Transistor Driver dc switching's output (s). dc switching'sThe supply and operating voltage of the dc control are 5.5V~28V. Qualified to work in a -5°C~125°C TJ dc switcher. This switching controller can switch at 200kHz~500kHz. Surface Mount makes it suitable for general dc dc regulator. The dcdc regulator features Current Limit, Enable, Frequency Control, Power Good, Soft Start for efficient switching control. The switch converters are connected to a DUAL SWITCHING CONTROLLER analog IC. Terminal (s) of the switching converters are designed at the QUAD position. 28 terminations with a variety of function. To name a few of the control techniques these dc dc converter ics adapt, it includes PULSE WIDTH MODULATION. 5V nominal DC switcher's voltage input. Other relevant dc to dc converter ics can be found by searching "LM2647". Switching converter has a total of 28 pins. Switching converter is a type of Switching Regulator or Controllers in particular. According to the test statistics, DC regulator outputs 5V voltage. The dc dc regulator's usual output current is 20A, which should be noted down when you start a project. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sThe max frequency of the pmic can reach 500kHz. It is suggested that users apply 28V to the voltage regulator dc to dc in order to run it safely and reliably in a circuit. The dc switching utilizes 2.5mA when it is in a dormant state.
