LM3557
Overview
The LM3557 is a complete solution for white LED drive applications. With minimal external component count, no DC current leakage paths to ground, cycleby-cycle current limit protection, and output overvoltage protection circuitry, the LM3557 offer superior performance and cost savings over standard DC/DC boost component implementations.
