The SGM62116 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 integrates 900mA typical average input current limit.
The SGM62116 adopts the peak current mode control with a fixed 2.4MHz switching frequency to regulate the output voltage. In addition, the SGM62116 offers configurable seamless transition PFM (pulse frequency modulation) mode or FPWM (forced PWM) mode via configuration of MODE/SYNC pin configuration. PFM enables higher light load efficiency, while FPWM mode ensures constant switching frequency throughout entire load range. External clock synchronization is also available with SGM62116.
The SGM62116 offers various protection features to improve device robustness. Integrated soft-start to reduce inrush current during startup, cycle-by-cycle over-current protection, over-voltage protection and thermal shutdown protection are implemented. In addition, the device features true load-disconnect when the EN pin is pulled low.
The device is available in a Green WLCSP-1.11×1.84-8B package.
