LXM15035_15135_En_datasheet.pdf
The LXM15135 is a high voltage, low dropout current regulator. The device is to drive up to 350mA average current with ±5% variation by an external resistor. LXM15135 can be widely and easily used in various LED lighting applications. Traditional current regulators usually have a potential over heat problem when LED supply voltage is far higher than a required forward voltage for a LED string. With an adaptive VD voltage adjustment technology, a common over-heat problem with current regulators will be eliminated or improved dramatically. However, a built-in thermal protection is still made to prevent the chip from the damage of over-heat. To provide maximum system protections and more reliable solutions for the demanding lighting applications, the LXM15135 is also to feature a LED short protection.
The LXM15135 is provided in a SOP8-EP package.
