MIC2298  
3.5A Minimum, 1MHz Boost High  
Brightness White LED Driver  
General Description  
Features  
The MIC2298 is a high power boost-switching regulator  
that is optimized for constant-current control. The MIC2298  
is capable of driving up to 2 series 1A white LED for  
photoflash, flashlight and other applications. The feedback  
voltage is only 200mV, minimizing ballast power dissipa-  
tion in constant-current control applications for improved  
operating efficiency.  
3.5A minimum switch current delivers at least 7W of  
output power over-temperature  
200mV ±10% feedback voltage  
2.5V to 10V input voltage  
Output voltage up to 30V (max)  
12-pin 3mm x 3mm leadless MLF® package  
Available output over-voltage protection (OVP)  
1MHz operation  
Programmable output current  
<1% line regulation  
1µA shutdown current  
The MIC2298 has a brightness pin that allows for a  
programmable torch mode as well full flash with a single  
pin when driving high current LEDs.  
The MIC2298 implements a constant frequency 1MHz  
PWM control scheme to make the smallest possible  
design.  
Over temperature protection  
Externally programmable soft-start  
Under-voltage lockout (UVLO)  
–40°C to +125°C junction temperature range  
The 2.5V to 10V input voltage range of MIC2298 allows  
direct operation from 1- and 2-cell Li Ion as well as 3- to 6-  
cell NiCad/NiMH/Alkaline battery sources. Maximum  
battery life is assured with a low 1µA shutdown current.  
The MIC2298 is available in a low profile 12-pin 3x3 MLF®  
package.
