LP55231SQE/NOPB Overview
The board's 24-WFQFN Exposed Pad package saves space. Mounting is done according to the Surface Mount method.It emerges as a DC DC Regulator with high efficiency.-30°C~85°C TA is the operating temperature and it works fine.Backlight provides many benefits.For its operation, terminations with a value of 0 are used.To form its configuration, there are 24 pins.It consists of 9 segments.The mount is in the direction of Surface Mount.Under the base part number LP55231, you'll find this LED driver.It is acceptable to have a maximum voltage of 5.5V.Additionally, it can be classified as Display Drivers based on its characteristics.The minimal input voltage is 2.7V.As a result, it is designed to operate at a minimal voltage of 2.7V to ensure the most efficiency possible.Whenever the maximum supply current is allowed, the value reaches 5.5V.If the maximum current supply is less than 750μA, this device provides high efficiency.A load can be supplied with 25.5mA current.As long as the switching frequency is maintained at 1.25MHz, this electronic component is able to perform all of its functions properly.It is capable of delivering all benefits of a LED driver when operating with the maximal output current of 25.5mA.In the absence of external factors, 800μA current is consumed.There is 5.5V voltage at the output terminal.If the output voltage exceeds 5.5V, it should be corrected.The voltage it outputs stays at 3.6V.
