LM2647LQ/NOPB Overview


In the 28-WFQFN Exposed Pad package, the switching controller meets most application requirements. dc motor controller is suitable for 2 output generation. Tape & Reel (TR) is the solid enclosure in which PMIC is packaged. Transistor Driver dc switching's outputs (s) are supported. dc controls with 5.5V~28V voltage are supplied and operated. Qualified to work in a -5°C~125°C TJ dc switcher. The switching controller can be switched at 200kHz~500kHz. The Surface Mount makes it ideal for general dc dc regulator. DCDC regulator is controlled efficiently by Current Limit, Enable, Frequency Control, Power Good, Soft Start. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. A switching converters's terminal (s) sits at the BOTTOM position. An array of 28 terminations of dc switching. These dc dc converter ics adapt a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's input voltageis set to 5V. Searching "LM2647" will return other relevant dc to dc converter ics. There are 28 pins on switching converter. A 5V voltage of DC regulator was detected in the test statistics. You should note down the dc dc regulator's usual output current of 20A when you start a project. It is set to 50 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. Because of DC switcher's Surface Mount, it is suitable for most prototype designs and applications. The max frequency of the pmic can reach 500kHz. For better satisfaction, the value of DC to DC voltage regulator is OUTPUT IS ADJUSTABLE DOWN TO 0.6V. In order to run the voltage regulator dc to dc safely and reliably, users are advised to apply 5.5V. When the dc switching is dormant, it uses 2.5mA. 500mA volts is the supply current.
