BOOST-UP VOLTAGE

CONVERTER FOR LED DRIVER



DESCRIPTION

The L5030 is a high efficiency boost converter operating in

current loop, based on a PFM mode to drive LEDs. The current

mode regulation allows the uniform brightness of LEDs. The wide

application of L5030 makes it suitable for many types of battery

applications such as Li-ions, Alkaline, or Sealed Lead Acid battery.

The combination of few external components and small package

size keeps the converter board area to a minimum in

space-restricted applications.
