MIC2288YML-TR

The MIC2288 is a 1.2 MHz PWM, DC/DC boost switching regulator available in low profile Thin SOT23 and 2 mm×2 mm DFN package options. High-power density is achieved with the MIC2288 device’s internal 34V/1A switch, allowing it to power large loads in a tiny footprint. The MIC2288 implements a constant frequency, 1.2 MHz PWM, Current-mode control scheme with 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 topology also reduces spurious switching noise and ripple to the input power source. The MIC2288 is available in a low profile 5-lead Thin SOT23 package and a 2 mm×2 mm 8-lead DFN leadless package. The DFN package option has an output overvoltage protection feature. The MIC2288 has a junction temperature range of -40°C to +125°C.
