AN-1697 LM4510 Evaluation Board
1 Introduction
The LM4510 is a current mode synchronous step-up DC/DC converter designed for organic LED
applications. The evaluation board is designed to provide adjustable output voltage from a single Li-Ion
battery. By default, output voltage is set to 16 V. Output voltage can be configured by choosing R

and
R
F2
. Loop compensation is achieved by R
