SGM61031

3A High Efficiency

Synchronous Buck Converter

GENERAL DESCRIPTION

FEATURES

● AHP-COT Architecture for Fast Transient Regulation

● 2.7V to 5.5V Input Voltage Range

● 3A Output Current

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.

● 100% Duty Cycle for Lowest Dropout

● Power-Save Mode for Light Load Efficiency

● Output Discharge Function

● Power Good Output

● Thermal Shutdown

To meet the requirements of system power rails, the

output capacitors with values above 100μF can be

used by the internal loop compensation.

● Available in a Green TDFN-2×2-8AL Package

APPLICATIONS

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.
