LM3557
Step-Up Converter for White LED Applications
General Description
The LM3557 is a complete solution for white LED drive
applications. With minimal external component 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 component implementations.
The LM3557 switches at a fixed-frequency of 1.25 MHz,
which allows for the use of small external components. Also,
the LM3557 has a wide input voltage range to take advan-
tage of multi-cell input applications. With small external com-
ponents, high fixed frequency operation, and wide input
voltage range, the LM3557 is the most optimal choice for
LED lighting applications.
