LM5155QDSSTQ1 Overview
As a result of 12-WFDFN Exposed Pad compact design, the switching controller is compatible with most applications. For outputs of 1, this dc motor controller is suitable. The pmic is packaged in Tape & Reel (TR) solid enclosure. Transistor Driver dc switching's outputs (s) are supported. 2.97V~45V is the operating voltage and supply voltage of the dc control. Suitable for work in a -40°C~150°C TJ dc switcher. Using this switching controller, it is possible to switch at 100kHz~2.2MHz. It is suitable for general dc dc regulator when it is set to Surface Mount, Wettable Flank. For efficient switching control, the dcdc regulator features Soft Start. Thare switch converters are connected to an analog integrated circuit (IC) of type SWITCHING CONTROLLER. Thare switching converters has a terminal (s) at DUAL . An array of 12 terminations of dc switching. Some of the control techniques used by these dc dc converter ics are PULSE WIDTH MODULATION. The DC switcher's nominal voltage is 12V. Searching "LM5155" will return other relevant dc to dc converter ics. It is recommended that the dc dc voltage regulator's minimum input voltage be 2.97V. The dc to dc regulator can only accept 45V input voltage. Automotive, AEC-Q100 series dc to dc voltage regulator belong to this series.
