350ma Constant Current Led Driver Ic

Running a series circuit helps to provide the same amount of current to each led.

350ma constant current led driver ic.

The specs on its little plate said uout was 4 5 vdc. You can also choose from 220v constant current led driver 1w 350ma as well as from 2 year constant current led driver 1w 350ma and whether constant current led driver 1w 350ma is 51 100w or 1 50w.

Integrated circuits ics pmic led drivers are in stock at digikey. A wide variety of constant current led driver 1w 350ma options are available to you such as lighting and circuitry design project installation. It is a high efficiency boost converter that operates from 1 or 2 nimh or alkaline cells and generates 350ma of constant current with up to 4v of compliance. 1 a 1000 ma there are also variable and selectable output current drivers.

That driver might work with 1 led but maybe not with 4 in a series. It contains a 100mω nfet switch and a 130mω pfet synchronous rectifier.

The drop across one white led is about 3 6 v and the drop across 4 of them is 4 3 6 v 14 4 v. These drivers vary the voltage along an electronic circuit which allows current to remain constant throughout the led system. The requirements of a lighting application often dictate what type of circuit can be used but if given the choice the most efficient way to run high power leds is using a series circuit with a constant current led driver. When using a constant current led driver observe the current requirements of your chosen led s.

The cc driver should then reflect that value output. A constant current led power supply works by varying the voltage along an electronic circuit and thus allows the current to remain constant throughout the led system. Leds data sheets state what they require with the value given in amps a or milliamps ma. Constant current led drivers maintain a fixed output current ma which is usually measures in milliamps ma or amps a and within a specified range of voltages.
