MIC2297  
40V PWM Boost Regulator  
White LED Driver  
General Description  
Features  
The MIC2297 is a 600KHz PWM boost-switching regulator  
that is optimized for driving 6-10 series white LEDs. With  
its internal 40V switch and a guaranteed switch current of  
1.2A, the MIC2297 easily drives a string of 10 white LEDs  
in series at 20mA, ensuring a high level of brightness and  
eliminating several ballast resistors.

2.5V to 10V input voltage range  
Output voltage up to 40V  
1.2A switch current  
600KHz PWM operation  
Trimmed 200mV feedback voltage  
Output over voltage protection (fixed or adjustable)  
PWM Brightness Control  
The MIC2297 implements constant frequency 600KHz  
PWM control. The high frequency PWM operation saves  
board space by reducing external component sizes. The  
added benefit of the constant frequency PWM operation is  
much lower noise and input ripple injected back to the  
battery source than with variable frequency topologies.  
DAC Brightness Control  
<1% line regulation  
1µA shutdown current  
Over temperature protection  
UVLO  
To optimize efficiency, the feedback voltage is set to  
200mV. This reduced voltage reduces the power  
dissipation in the current set resistor, and allows the lowest  
total output voltage, hence minimal current draw from the  
battery.  
2.5mm x 2.5mm MLF™-10L package  
–40oC to +125oC junction temperature range  
Applications  
The MIC2297 is available with output over-voltage  
protection that protects the IC and external components in  
case of open LED conditions.
