LM3554 and LM3556 have similar functions but very different register map. This driver is a general version for LM355x,lm3554 and lm3556,led chips of TI. lm3556 driver can be replaced by this driver.
LM3554 : The LM3554 is a 2 MHz fixed-frequency synchronous boost converter with 1.2A dual high side led drivers. Datasheet: www.ti.com/lit/ds/symlink/lm3554.pdf
LM3556 : The LM3556 is a 4 MHz fixed-frequency synchronous boost converter plus 1.5A constant current driver for a high-current white LED. Datasheet: www.national.com/ds/LM/LM3556.pdf
