Features & Applications

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 1 A white LED for photoflash, flashlight and other applications. The feedback voltage is only 200 mV, 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 1 MHz PWM control scheme to make the smallest possible design. The 2.5 V to 10 V 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 1 µA shutdown current. The MIC2298 is available in a low profile 12-pin 3x3 MLF ® package.
