2A Dual Flash LED Driver System with I2C Compatible Interface com March 6, 2008 LM3553 1.
2A Dual Flash LED Driver System with I2C Compatible Interface General Description The LM3553 is a fixed frequency, current mode step-up DC/ DC converter with two regulated current sinks.
The device is capable of driving loads up to 1.
2A from a single-cell Li-Ion battery.
One or more high current flash LEDs can be driven in series either in a high power Flash mode or a lower power Torch mode controlled by either an internal register or the FEN pin.
Additionally a low current (20mA) indicator mode and a fixed output voltage mode are also available.
The LM3553 has 128 current lev...
