L5030
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.
FEATURES
* Inductor based converter brings up to 92% efficiency
* +0.8V to +6.0V input voltage range
* 0.92V guaranteed start up input voltage
* Boost up control using PFM
* Constant output current regulation
