Features & Applications

The MIC2299-15YML TR is a high power boost-switching regulator that is optimized for constant-current control. The MIC2299 is capable of driving up to 2 series 1 A white LED for photoflash and other applications. The feedback voltage is only 200 mV, minimizing power dissipation in constant-current control applications, and hence extends battery life.

The MIC2299 has a brightness pin that allows for a programmable torch mode as well as full flash with a single pin when driving high current LEDs. The MIC2299 implements a constant frequency 2 MHz PWM control scheme to make the smallest possible design. The MIC2299’s 2 MHz operation avoids signal interference in the AM band. The 2.5 V to 10 V input voltage range of MIC2299 allows direct operation from 1- and 2-cell Li-Ion as well as 3- to 4-cell NiCad/ NiMH/ Alkaline or lithium batteries. Maximum battery life is assured with a low 1 uA shutdown current. The MIC2299 is available in a low profile 12-pin 3 mm x 3 mm MLF ® package.
