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.
