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.
