MIC3287

1.2MHz PWM White LED Driver with OVP in

Thin SOT-23 and 2mm x 2mm MFL

General Description

The MIC3287 is a 1.2MHz pulse width modulated (PWM)

step-up switching regulator that is optimized for constant cur-

rent white LED driving applications. With a switch current of

over 350mA, the MIC3287-24 drives a string of up to 4 white

LEDs in series, ensuring uniform brightness and eliminating

several ballast resistors.

The MIC3287 implements a constant frequency 1.2MHz PWM

current-mode control scheme. The high frequency PWM op-

eration saves board space by reducing external component

sizes. The added benefit of the constant frequency PWM

control scheme as opposed to variable frequency control

schemes is much lower noise and input ripple injected back

to the battery source. To optimize efficiency, the feedback

voltage is set to only 250mV. The MIC3287 is also available

with a maximum 24V over-voltage protection.

The MIC3287 is available in low profile Thin SOT-23 5-pin

and Thin SOT-23 6-pin packages. The MIC3287 has a junc-

tion temperature range of –40°C to +125°C.
