Microchip | MIC2288YD5-TR

The MIC2288YD5 TR is a 1.2 MHz PWM, DC/DC boost switching regulator available in low-profile Thin SOT-23 and 2 mm × 2 mm MLF™ package options. High power density is achieved with the MIC2288’s internal 34 V/1 A 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.
