The MIC2288 is a 1.2MHz pulse-width modulation (PWM), DC/DC boost switching regulator. High power density is achieved with the MIC2288's internal 34V/1A switch, allowing it to power large loads in a tiny footprint. The MIC2288 implements a constant frequency 1.2MHz 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 has a junction temperature range of -40°C to +125°C.
