LM3500 Synchronous Step-up DC/DC Converter

The LM3500 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 (500mV), power efficiency of the LM3500 ci.
