CONSTANT CURRENT BOOST CONVERTER  
FOR 1 TO 4 WHITE LEDS  
FEATURES  
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 cell, and its switching frequency is  
fixed at 1 MHz.

Up to 4 LEDs at 2.8V Supply  
High Efficiency (85%)  
Output Over Voltage Protection  
HV Internal Switch  
The AAT1500 offers a low 0.25V reference, which  
minimizes power loss in the current setting resistor and  
improves efficiency. Except in SOT23-5 package,  
protection features include output over voltage  
protections. The AAT1500 consists of a 0.1µA shutdown  
current, and HV internal switch. Input supply range  
allows operation from 2.6V to 6V.  
1 MHz PWM Switching Frequency  
Uses Tiny 1 mm Height Inductor  
2.6V to 6V Input Range  
0.1µA Shutdown Current  
SOT23-5 , SOT23-6,TSOT23-6, and VSON8  
Packages Available  
The AAT1500 is available in SOT23-5, SOT23-6,  
TSOT23-6 and VSON8 packages.
