General Description

The AAT1500 is a step-up converter that provides a solution to drive 1 to 4 white LEDs with a constant current from a Lithium Ion cell, and its switching frequency is fixed at 1 MHz.

The AAT1500 offers a low 0.25V reference, which minimizes power loss in the current setting resistor and improves efficiency.

Except in SOT-25 package, protection
