MIC2296YD5-TR

The MIC2296 is a 600kHz, PWM dc/dc boost switching regulator available in a 2mm×2mm MLF package option. High power density is achieved with the MIC2296’s internal 34V / 1.2A switch, allowing it to power large loads in a tiny footprint. The MIC2296 is a version of the MIC2295 1.2MHz, PWM dc/dc boost switching regulator, that offers improved efficiency resulting from 600kHz operation. The MIC2296 implements constant frequency 600kHz PWM current mode control. The MIC2296 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 MIC2296 is available in a low-profile Thin SOT23 5-pin package and a 2mm x2mm 8-pin MLF leadless package. The 2mm×2mm MLF package option has an output over-voltage protection feature. The MIC2296 has an operating junction temperature range of -40°C to +125°C
