The SGM62125 is a 4-switch Buck-Boost converter 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 2.5A output current range.
The SGM62125 is 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. The device implements peak current mode control architecture to achieve excellent load/line transient performance across the operating voltage range.
Dynamic voltage scaling is available via I2C controlled output voltage registers. The ADDR pin allows the programmability for I2C slave address and default start-up voltage.
The SGM62125 implements robust protection features such as over-temperature, input over-voltage, over-current, and short-circuit hiccup protections to protect device against unexpected system failure.
The SGM62125 is available in a Green WLCSP-1.46×2.3-15B package. High integration provides a compact solution with only four external components, allowing implementation in a PCB area as small as 39mm2.
