The LM3557 is a plete solution for white LED drive applications. With minimal external ponent count, no DC current leakage paths to ground, cycle-by-cycle current limit protection, and output over-voltage protection circuitry, the LM3557 offer superior performance and cost savings over standard DC/DC boost ponent implementations. The LM3557 switches at a fixed-frequency of 1.25 MHz, which allows for the use of small...
