MIC2299  
3.5A Minimum, 2MHz High Brightness  
LED Driver  
General Description  
Features  
The MIC2299 is a high power boost-switching regulator  
that is optimized for constant-current control. The MIC2299  
is capable of driving up to 2 series 1A white LED for  
photoflash and other applications. The feedback voltage is  
only 200mV, minimizing power dissipation in constant-  
current control applications, and hence extends battery  
life.  
Programmable current control  
200mV ±10% feedback voltage  
2.5V to 10V input voltage  
Output over-voltage protection (OVP)  
Output voltage up to 30V (max)  
Fixed 2MHz Operation  
The MIC2299 has a brightness pin that allows for a  
programmable torch mode as well as full flash with a  
single pin when driving high current LEDs.  
Guaranteed 3.5A switch current over-temperature  
Solution size of just 0.25in2 (1.6cm2)  
Output power range of 7W to 12W  
<1% line regulation  
1µA shutdown current  
Over temperature protection  
The MIC2299 implements a constant frequency 2MHz  
PWM control scheme to make the smallest possible  
design. The MIC2299’s 2MHz operation avoids signal  
interference in the AM band.  
The 2.5V to 10V input voltage range of MIC2299 allows  
direct operation from 1- and 2-cell Li-Ion as well as 3- to 4-  
cell NiCad/ NiMH/ Alkaline or lithium batteries. Maximum  
battery life is assured with a low 1uA shutdown current.  
Externally programmable soft-start  
Under-voltage lockout (UVLO)  
12-pin 3mm x 3mm leadless MLF® package  
–40°C to +125°C junction temperature range  
The MIC2299 is available in a low profile 12-pin 3mm x  
3mm MLF® package.
