Device Overview

Summary

The MIC2292 and MIC2293 are high frequency, pulse-width modulator (PWM) boost regulators optimized for constant-current, white LED driver applications. Because of their constant PWM switching frequencies of 1.6MHz and 2MHz, respectively, the MIC2292/93 can use the smallest external components, allowing designers to avoid sensitive IF bands in their RF applications.

The products feature an internal Schottky diode and two levels of output overvoltage protection allowing a small size and efficient DC/DC solution that requires only four external components.

The 2.5V to 10V input voltage range of MIC2292/3 allows direct operation from 1- and 2-cell Li-Ion as well as 3- to 4-cell NiCad/NiMH/Alkaline batteries.
