DC/DC buck power modules fit tight spaces

Micrel’s family of low-profile step-down power modules integrates a synchronous buck regulator with an inductor into a 2.5×3×1.1-mm QFN package for the 1-A MIC33163/33164 and a 2.5×3×1.9-mm QFN package for the 2-A MIC33263/33264. The modules offer 100% duty cycle operation and accommodate an input voltage range of 2.7 V to 5.5 V. Incorporating Micrel’s FleaFET …
