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.

The MIC2605 and MIC2606 implement constant

frequency 1.2 MHz and 2 MHz (respectively) PWM

current mode control. The MIC2605 and MIC2606 offer

internal compensation with 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 and MIC2606 are each available in an

8-lead 2 mm × 2 mm TDFN leadless package. This

package has an output overvoltage protection feature.

The MIC2605 and MIC2606 both have operating

junction temperature ranges of –40°C to +125°C.
