1.4A BOOST FOR WHITE LED

DRIVER



DESCRIPTION

The UTC L5104 is a high frequency, asynchronous boost

converter. The internal MOSFET can support up to 8 White LEDs

for backlighting and OLED power application, and the internal soft

start function can reduce the inrush current.

SOT-26

The UTC L5104 uses current mode, 1.0MHz fixed frequency

architecture to regulate the LED current, which is set through an

external current sense resistor. Its low 300mV feedback voltage

reduces power loss and improves efficiency. The OVP pin monitors

the output voltage and turns off the converter if an over-voltage

condition is present due to an open circuit condition. The UTC

L5104 includes under-voltage lockout, current limiting and thermal

shutdown protection preventing damage in the event of an output

overload.


