General Description
The MIC2605 and MIC2606 are PWM DC/DC boost switching regulators each available in a 8-lead 2 mm x 2 mm TDFN package. The only difference between the 2 versions of the device is the switching frequency: The MIC2605 runs at 1.2 MHz, while the MIC2606 runs at 2 MHz. High power density is achieved with the internal 40V switch and 0.5A Schottky diode in both the MIC2605 and MIC2606, allowing them to power large loads in a tiny footprint.
