LM27952SD/NOPB Overview
14-WFDFN Exposed Pad package saves space on the board. Surface Mount represents this mounting method.It emergys as a DC DC Regulator with high efficiency and reliable performance.At -40°C~85°C TA, the led driver is capable of operating.Backlight has many advantages.In this case, there are 14 terminations.With a base of 14, this LED light driver is configured.There are 4 segments.It has been mounted on Surface Mount.LM27952 is the base part number for the LED driver.The supply voltage of 5.5V is an acceptable maximum value.The device has a voltage output of 2.5V~3.9V volts.14 pins are used on the device.Furthermore, it can be categorized as Display Drivers based on its characteristics.At a voltage of 3V, it operates at a minimal input voltage.For highest efficiency, it works with a minimal supply voltage of 3V.Currently, the supply current can only reach 5.5V.If the maximum current supply is less than 1.7mA, this device provides high efficiency.You can supply 120mA current to the load.It's possible for this electronic component to fully function when the switching frequency is maintained at 750kHz.There is no external factor that consumes current when there is 1.3mA current consumption.
