350ma constant current led driver ic.

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. The fixed switching frequency is internally set t. Running a series circuit helps to provide the same amount of current to each led. If so that might the current sensing mechanism you are looking to discover.

A wide variety of constant current led driver 1w 350ma options are available to you such as lighting and circuitry design project installation. 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. That driver might work with 1 led but maybe not with 4 in a series. Ic led drvr lin dim 350ma sot26 81 000 immediate 99 000 factory stock available.

Higher current ratings do make the led brighter but if not regulated the led will draw more current than it is rated for. Mean well s ap constant current driver is a good example shown below. 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. These drivers vary the voltage along an electronic circuit which allows current to remain constant throughout the led system.

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. The ltc3490 provides a constant current drive for 1w led applications. Integrated circuits ics pmic led drivers are in stock at digikey. 1 a 1000 ma there are also variable and selectable output current drivers.

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.

The specs on its little plate said uout was 4 5 vdc. 12v led drivers 24v led drivers 350ma constant current drivers 500ma constant current drivers 700ma constant current drivers led controllers. 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.
