MIC2288YD5-TR 1.2A High-Frequency Boost Switching Regulator IC
The MIC2288YD5-TR is a compact, high-efficiency 1.2 MHz PWM DC/DC boost switching regulator designed to deliver high power density in space-constrained applications. Featuring an integrated 34V/1A internal switch, this device can efficiently power large loads within a tiny footprint, making it ideal for portable and industrial power systems. The MIC2288 operates using a constant-frequency PWM current-mode control with internal compensation, ensuring excellent transient response, tight output regulation, and superior stability across operating conditions.
The high 1.2 MHz switching frequency allows the use of small, low-profile inductors and capacitors, minimizing board area while achieving clean, low-noise operation. The fixed-frequency PWM topology also significantly reduces input ripple and unwanted switching noise, enhancing system reliability and performance. Available in a 5-lead Thin SOT-23 and 2mmx2mm 8-lead DFN package, the MIC2288 offers flexibility for various design requirements. The DFN package version includes additional output overvoltage protection, ensuring safe operation under transient conditions. Operating over a 40 C to+125 C junction temperature range, the MIC2288YD5-TR provides robust, efficient power conversion for battery-powered and portable devices.
