LM2647LQ Product Details

LM2647LQ Overview


It comes in the 28-WFQFN Exposed Pad package, which makes switching controller suitable for most applications. It is sufficient to generate 2 outputs with this dc motor controller. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 5.5V~28V. Qualified to work in an dc switcher with -5°C~125°C TJ. The switching controller can be switched at 200kHz~500kHz. dc dc regulators can be carried out with Surface Mount. Current Limit, Enable, Frequency Control, Power Good, Soft Start provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a DUAL SWITCHING CONTROLLER output. There are a QUAD terminal on the switching converters. Different dc switching's functions can be applied to 28 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input of 5V. LM2647 can be searched for other relevant dc to dc converter ics. In total, switching converter has 28 pins. Switching converter type is specifically Switching Regulator or Controllers. Statistically, DC regulator outputs 5V volts. In most cases, the output current of the dc dc regulator will be 20A, so note that when you start the project. DC switcher's Surface Mount qualifies it for most applications and prototypes. 345kHz is the frequency of the switching controller. For safe and reliable operation in a circuit, voltage regulator dc to dc is suggested that users apply 28V. Dormant dc switchings use 2.5mA.
