PAM2804 Description
The PAM2804 is a step-down constant current LED driver. When the input voltage is down to lower than LED forward voltage, then PAM2804 goes into LDO mode. Pin Assignments Top View TSOT25 The PAM2804 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 standard power sources.
