SG-Micro SGM62117 | Demoboard SGM62117 High-Efficiency Buck-Boost Converter

High-Efficiency Buck-Boost Converter

Overview

TopologyBuck-Boost Converter
Input voltage2.2-5.5 V
Output 15.2 V / 2 A
IC revisionA

Description

The SGM62117 is a synchronous 4-switch Buck-Boost converter which is suitable for battery operated applications. The device’s programmable light load PFM mode and low quiescent current (18μA, TYP) offer above 90% efficiency in the 10mA to 2A output current range. The output voltage is programmable via external feedback resistor divider.The SGM62117 can operate in Buck, Boost or a novel 4-cycle Buck-Boost mode when the input voltage is close to or equal to the output voltage. The device implements pre-defined mode transition thresholds to avoid undesired toggling within modes to reduce output voltage ripple.
