Introduction

AI Translation

The SC21150 is an ultra-high efficiency 1.2A DC/DC buck regulator available in a tiny CSP package. These features make the SC21150 family perfect for small form factor portable applications where long battery life is essential. SC21150 is an Adaptive On-Time 4MHz switching regulator at full load conditions. Under light load conditions, it seamlessly transitions into 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. A Forced PWM input allows continuous switching under all load conditions. The SC21150 is highly configurable with a wide range of factory options including internal Soft Start times, fixed or adjustable output voltage, automatic output discharge, and a Forced PWM input. Additional options include exchanging the Forced PWM input for externally programmed Soft Start or a Power Good indicator. Operating frequency options are 2.2, 3, and 6MHz. The SC21150 is offered in an ultra-small WLCSP 6-Bump 0.75mm x1.11mm package with a bump pitch of 0.35mm. The SC21150 operating temperature range is -40C to +85C.
