圣邦微代理sgm62110S  3A电流的升降压一体电源芯片，***静态电流20UA

The SGM62110 and SGM62111 are 4-switch Buck-Boost 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 current offer 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.

Dynamic voltage scaling is enabled via VSEL pin and I2C controlled output voltage registers which allows the device to toggle output voltages based on application needs.

The SGM62110 and SGM62111 implement robust protection features such as over-temperature, input over-voltage and output over-current protections to protect device against unexpected system failure.

The SGM62110 and SGM62111 are available in a small Green WLCSP-2.21×1.40-15B package. High integration provides a compact solution with only four external components, allowing implementation in a PCB area as small as 39mm2.
