„ 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 +8.0V input voltage range
* 0.92V guaranteed start up input voltage
* Boost up control using PFM
* Constant output current regulation
