LM51551DSST Product Details

LM51551DSST Overview


It comes in the 12-WFDFN Exposed Pad package, which makes switching controller suitable for most applications. It is sufficient to generate 1 outputs with this dc motor controller. Packaging for the pmic consists of Cut Tape (CT) solid enclosures. The program can handle Transistor Driver dc switching's outputs (s). dc control's supply and operating voltages are 2.97V~45V. Qualified to work in an dc switcher with -40°C~125°C TJ. The switching controller can be switched at 100kHz~2.2MHz. dc dc regulators can be carried out with Surface Mount. Soft Start provides dcdc regulator efficient switching control. The switch converters are connected to an analog IC with a SWITCHING CONTROLLER output. There are a DUAL terminal on the switching converters. Different dc switching's functions can be applied to 12 terminations. Some of the control techniques adapted by these dc dc converter ics include PULSE WIDTH MODULATION. DC switcher's voltage input of 12V. LM51551 can be searched for other relevant dc to dc converter ics. This dc dc voltage regulator should be powered by a voltage of 2.97V. This dc to dc regulator accepts only 45V input voltage at most.
