LQH31MN220J03L - Brand New Murata Electronics Fixed Inductors
-
```html
Description
The LQH31MN220J03L is a fixed inductor electronic component model. It is a step-up DC/DC converter designed specifically for driving white LEDs with a constant current. The converter can drive two, three, or four LEDs in series from a Li-ion cell, resulting in uniform brightness without the need for ballast resistors. The device switches at 1.2 MHz, allowing for the use of small external components. The output capacitor required for this converter can be as small as 0.22μF, saving both space and cost compared to other solutions. With a low 95mV feedback voltage, power loss in the current setting resistor is minimized, enhancing overall efficiency.
