The MIC2605/6 is a 1.2MHz/2MHz, PWM DC/DC boost switching regulator. High power density is achieved with the MIC2605/6's internal 40V/0.5A switch and Schottky diode, allowing it to power large loads in a tiny footprint.

The MIC2605/6 implements constant frequency 1.2MHz/2MHz PWM current mode control. The MIC2605/6 offers internal compensation that offers excellent transient response and output regulation performance. The high frequency operation saves board space by allowing small, low-profile external components. The fixed frequency PWM scheme also reduces spurious switching noise and ripple to the input power source.

The MIC2605/6 has an operating junction temperature range of -40°C to +125°C.
