SGM61012S
1.2A/2A High-Efficiency Buck Converter with AHP-COT Mode
1.2A/2A High-Efficiency Buck Converter with AHP-COT Mode
GENERAL DESCRIPTION

The SGM61012S and SGM61022S are efficient high-frequency synchronous Buck converters with an input voltage range of 2.3V 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.

Setting the MODE pin can enable deep sleep mode (DSM). This device operates with an ultra-low quiescent current, and it can maintain high efficiency at very low load. This function keeps the standby current at its lowest level, and can increase the standby time of battery-powered application. 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 SGM61012S and SGM61022S are available in a Green TDFN-2×2-8AL package.
