Eutech Microelectronics EUP2586

The EUP2586 is a high frequency, asynchronous boost converter designed for driving white LED arrays. With integrated 0.19Ω power switch and 2A current limit, the EUP2586 provides enough driving capability for 7”~10” LCD backlighting(13 strings of 3 or 4 LEDs each). The device uses current mode, fixed frequency architecture to regulate the LED current, which is measured through an external current sense resistor.

DESCRIPTION

Its low 200mV feedback voltage reduces power loss and improves efficiency. With the built-in over-voltage protection function (OVP), the SW pin monitors the output voltage and turn off the device if an over-voltage condition is present due to an open circuit condition. Other features include soft start, over-current limiting, thermal protection and under-voltage lockout. The EUP2586 is available in the tiny TSOT23-5 package to provide the best solution for PCB space saving and total BOM cost.
