600mA, 1.8V to 5.5V

Synchronous Buck Converter

GENERAL DESCRIPTION

FEATURES

The SGM61006 is a high efficiency and miniature size

synchronous Buck converter for low input voltage

applications. This high frequency device does not need

external compensation and is a perfect solution for

compact designs. The 1.8V to 5.5V input voltage range

is suitable for kinds of battery applications. The

minimum input voltage can be as low as 1.6V after

startup. It operates in PWM mode at heavy loads and

automatically enters power-save mode (PSM) at light

loads to maintain its high efficiency.

● 1.8V to 5.5V Input Voltage Range

● 0.5V to V_INAdjustable Output Voltage

● AHP-COT Architecture for Fast Transient

Regulation

● 3.5MHz Switching Frequency

● Up to 90% Efficiency

● Low R_DSONMOSFET Switches (100mΩ/95mΩ)

● 26μA (TYP) Operating Quiescent Current

● Power-Save Mode for Light Load Efficiency

● 100% Duty Cycle for Lowest Dropout

● Output Discharge Function

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 device is

available in a Green WLCSP-0.9×1.3-6B-A package.

● Power Good Output

● Thermal Shutdown Protection

● Available in a Green WLCSP-0.9×1.3-6B-A
