LM5155DSSR Overview
With its 12-WFDFN Exposed Pad package, the switching controller fits the needs of most applications. There is enough capacity in the dc motor controller to generate the output for the 1 input. Packaging for the pmic consists of Tape & Reel (TR) solid enclosures. With Transistor Driver dc switching's output (s), it is able to handle it. DC control operates at 2.97V~45V volts and has 2.97V~45V supply voltage. Worked in an dc switcher with a -40°C~125°C TJ rating. In this switching controller, the switch can be set to 100kHz~2.2MHz. The Surface Mount allows it to be used for dc dc regulator in general. The dcdc regulator features Soft Start for efficient switching control. An analog IC SWITCHING CONTROLLER is connected to the switch converters. There are a DUAL terminal on the switching converters. The 12 terminations can be used for a wide range of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. DC switcher's input voltageis set to 12V. Other relevant dc to dc converter ics can be found by searching "LM5155". It is recommended that the input voltage of the dc dc voltage regulator be 2.97V. The dc to dc regulator is limited to 45V input voltage.
