Introduction

AI Translation

The SC21152 is an ultra high efficiency 1.2A DC/DC buck regulator available in a small MLPD package. These features make the SC21152 perfect for small form factor consumer applications where high efficiency is essential. SC21152 is an Adaptive On-Time 4MHz switching regulator at full load conditions. Under light load conditions it transitions into PFM Power Save Mode and reduces switching frequency thus saving energy. High switching frequency operation allows the use of a very small 0.47μH inductor along with small input and output capacitors to minimize overall circuit size. The SC21152 is highly configurable with a wide range of factory options including internal soft start time, fixed or adjustable output voltage, automatic output discharge, and switching frequency. The SC21152 is offered in a small 6-Lead 1.5mm x 2mm MLPD package.
