350ma constant current led driver ic.

Ic led driver offline 2a 8so 2 500 immediate 100 000 factory stock. The fixed switching frequency is internally set t. 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. 12v led drivers 24v led drivers 350ma constant current drivers 500ma constant current drivers 700ma constant current drivers led controllers.

Integrated circuits ics pmic led drivers are in stock at digikey. The specs on its little plate said uout was 4 5 vdc. These drivers vary the voltage along an electronic circuit which allows current to remain constant throughout the led system. The cc driver should then reflect that value output.

Leds data sheets state what they require with the value given in amps a or milliamps ma. Mean well s ap constant current driver is a good example shown below. 100 240v ac dc 6 10 x3w 18w 20w 21w 24w 27w 30w power supply 600 ma lighting transformer for high power 20 w cob chips plastic case. 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.

Dimmers rgb controllers wifi controllers repeater amplifiers sensors dmx controllers dali controllers switches sockets led peripherals project gallery sales lighting design blog. The ltc3490 provides a constant current drive for 1w led applications. 1 a 1000 ma there are also variable and selectable output current drivers. A wide variety of constant current led driver 1w 350ma options are available to you such as lighting and circuitry design project installation.

When using a constant current led driver observe the current requirements of your chosen led s. Ic led drvr lin dim 350ma sot26 81 000 immediate 99 000 factory stock available. 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. If so that might the current sensing mechanism you are looking to discover.

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. 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. 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.
