SGM61031
3A High Efficiency Synchronous Buck Converter
3A High Efficiency Synchronous Buck Converter
GENERAL DESCRIPTION

The SGM61031 is an efficient high frequency synchronous Buck converter with an input voltage range of 2.7V to 5.5V and a wide output current range that is optimized for compact solutions. It operates in PWM mode at heavy loads and automatically enters power-save mode (PSM) at light loads to maintain its high efficiency.

To meet the requirements of system power rails, the output capacitors with values above 100μF can be used by the internal loop compensation.

With its adaptive hysteresis and pseudo-constant on-time control (AHP-COT) architecture, the load transient performance is excellent and the output voltage regulation accuracy is achieved.

The SGM61031 is available in a Green TDFN-2×2-8AL package.
