SGM62112 - 1.8A Switch Current Single Inductor Buck-Boost Converter

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.

Features

  • to improve device robustness such as soft-start to reduce inrush current during startup, cycle-by-cycle over-current protection and thermal shutdown protection. In addition, the device features true load disconnect when the EN pin is pulled low. The SGM62112 is available in a Green TDFN-3×3-10L package.

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 PFM (pulse frequency modulation) mode via MODE/SYNC pin configuration.
