Description:

Step-down constant current led driver.

LM3842, step-down constant current LED driver

The LM3842 is a step-down constant current LED driver.

When the input voltage down to lower than LED forward voltage, then LM3842 run into LDO mode.

The LM3842 supports a range of input voltages from 2.5V to 6.0V, allowing the use of a single Li+/Li-polymer cell, 3AA or 4AA cell, USB, and other stan
