MIC2295

The MIC2295 is a 1.2Mhz, PWM DC/DC boost switching regulator available in low profile Thin SOT23 and 2mm x 2mm MLF® package options. High power density is achieved with the MIC2295's internal 34V / 1.2A switch, allowing it to power large loads in a tiny footprint.

The MIC2295 implements constant frequency 1.2MHz PWM current mode control. The MIC2295 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 MIC2295 is available in a low-profile Thin SOT23 5-lead package and a 2mm x 2mm 8-lead MLF® leadless package. The 2mm x 2mm MLF® package option has an output over-voltage protection feature.

The MIC2295 has an operating junction temperature range of -40°C to +125°C.
