Evaluating LM3554 synchronous boost converter

Keywords:synchronous boost converter? LED? I2C?

The LM3554 Evaluation Board is designed to fully evaluate the LM3554 synchronous boost converter with dual 600mA High Side Flash LED Drivers and I2C Compatible Interface.

The board comes equipped with two LXCL-PWF4 Flash LEDs from Lumiled and an additional LED (LEDI) as an Indicator LED. The Flash Button demonstrates the Hardware Flash feature of the LM3554 and when pushed, turns on both Flash LEDs at the programmed Flash current. There are two 10k pull-up resistors on the board for the I2C clock and data lines (SDA and SCL). Additionally, there is a 10k pull-up (R_RESET) that pulls the HWEN pin high during startup. Each Input and/or output from the LM3554 has its own separate header to serve as a test-point.
