Description
General part information
MIC2298 Series
The MIC2298 is a high power boost-switching regulator that is optimized for constant-current control. The MIC2298 is capable of driving up to two 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.
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.
