com Synchronous Step-up DC/DC Converter for White LED Applications LM3501 Synchronous Step-up DC/DC Converter for White LED Applications General Description 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 circuit has been optimized for lighting applications in wireless phones and other portable products (single cell Li-Ion or 3-cell NiMH battery supplies).
The LM3501 operates with a fixed 1 MHz switching frequency.
