SG-Micro SGM62110 | Demoboard SGM62110 2.5A Buck-Boost Converters

Description

The SGM62110 and SGM62111 are 4-switch BuckBoost converters with programmable I2C interface for simple configuration of integrated rich features. Synchronous rectification improves system efficiency which is friendly for battery operated applications. In addition, the programmable light load PFM (pulse frequency modulation) mode and low quiescent currentoffer above 90% efficiency in the 10mA to 2A output current range.The SGM62110 and SGM62111 are capable to regulate the output voltage when the input voltage is below, above or equal to the output voltage. The mode transition is also optimized to ensure smooth operation and reduce output voltage ripple.
