APW7208 power management IC can drive 6 series white LED

LED power management IC APW7208, APW7208 is a fixed 1MHz switching frequency, current control mode DC/DC boost module, built in N channel switch can drive 6 series white light. The APW7208 can operate between 2.5V to 6V input voltage range, suitable for use in a single lithium battery powered applications.

1MHz switching frequency can effectively reduce the external inductance and capacitance of the volume. Built in 28V over voltage protection function, can avoid the empty load and produce unexpected high voltage. The highest efficiency of 88%, 0.25V provides internal reference voltage as LED limiting can get the highest efficiency, and prolonging the service life of the battery, the use of SOT-23-6 APW7208 packaging are of great help to save board space.
