SGM61012/SGM61022

1.2A/2A High-Efficiency

Buck Converters with AHP-COT Mode

GENERAL DESCRIPTION

FEATURES

● Input Voltage Range: 2.3V to 5.5V

● Output Current:

The SGM61012 and SGM61022 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.

SGM61012: 1.2A

SGM61022: 2A

● 8.5μA (TYP) Ultra-Low Quiescent Current in DSM

● AHP-COT Architecture

● Fast Transient Regulation

● 100% Duty Cycle Capability

● High-Efficiency DSM under Light Load

● Output Discharge

● Short-Circuit Protection

● Power Good Output

● Thermal Shutdown

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.

● 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.

General Purpose Point-of-Load Power Supplies

Battery-Powered Applications

The SGM61012 and SGM61022 are available in a

Green TDFN-2×2-8AL package.
