LINEAR INTEGRATED CIRCUIT
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.
