Datasheet Summary
SGM62112 1.8A Switch Current Single Inductor
Buck-Boost Converter
GENERAL DESCRIPTION
The SGM62112 is a fully-integrated synchronous Buck-Boost converter which is capable of operating from 1.8V to 5.5V input and suitable for battery powered applications such as 1-cell Li-Ion battery, 2-cell or 3-cell Alkaline/NiMH batteries. The device supports up to 1200mA output current at higher than 3.8V input voltage, and 800mA output current at higher than 2.5V input voltage.
The SGM62112 adopts the current mode control with a fixed 1.4MHz (TYP) switching frequency to regulate the output voltage. In addition, the SGM62112 offers configurable light load PWM (pulse width modulation) operation or auto...
