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.
The LM3557 switches at a fixed-frequency of 1.25 MHz, which allows for the use of small external components.
