LM51551DSSR Overview
It comes in a 12-WFDFN Exposed Pad package, so switching controller can be used for most applications. For outputs of 1, this dc motor controller is suitable. Tape & Reel (TR) solid enclosure protects the pmic. A total of Transistor Driver dc switching's outputs can be handled by it. Voltages 2.97V~45V are the dc control's supply voltage and operating voltage, respectively. Worked in a -40°C~125°C TJ dc switcher before. In this switching controller, the switch can be set to 100kHz~2.2MHz. Switching control is made easier with the dcdc regulator's Soft Start. Switch converters are connected to ICs with SWITCHING CONTROLLER analog outputs. There are a DUAL terminal on the switching converters. 12 terminations with a variety of function. A few of the control techniques these dc dc converter ics adapt include PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. Other relevant dc to dc converter ics will be returned if you search "LM51551". dc dc voltage regulators should have a minimum input voltage of 2.97V. Voltages 45V are the maximum that the dc to dc regulator will accept.
