LM3501, Synchronous Step-up DC/DC Converter
The LM3501 is a fixed-frequency step-up DC/DC converter that is ideal for driving white LEDs for display backlighting and other lighting functions.
With fully intergrated synchronous switching (no external schottky diode required) and a low feedback voltage (515 mV), power efficiency of the LM3501 c
LM3501 Features
* n Synchronous rectification, high efficiency and no external schottky diode required n Uses small surface mount components n Can drive 2-5 white LEDs in series (may function with more low VF LEDs) n 2.7V to 7V input range n True shutdown isolation, no LED leakage current n DC voltage LED current con
