GENERAL DESCRIPTION

The SGM6012 is a 1.6MHz constant frequency, current

mode, synchronous, step-down switching regulator. It

can deliver 800mA load current from 2.5V to 5.5V input

voltage, and the output voltage can be as low as 0.6V.

The high switching frequency minimizes the sizes of

inductor and capacitor. Integrated power MOSFETs

and internal compensation make the SGM6012 simple

to use and fit the total solution in a compact space.

The SGM6012 can operate at a low dropout for the 100%

duty cycle, which can conserve the battery life of

portable devices. The synchronous architecture

eliminates the external Schottky diode, and achieves

over 90% of the power conversion efficiency. With low

output ripple voltage at light load, the 30μA quiescent

current and less than 1μA shutdown current make

SGM6012 the ideal power supply solution for portable

applications.

SGM6012 is available in both adjustable and fixed

(1.2V, 1.8V, 3.3V) output voltage versions. It is

available in the Green TSOT-23-5 package. It is rated

over the -40℃ to +85℃ temperature range.
