GENERAL DEscriptION

The SGM6011 is a high-efficient monolithic synchronous buck converter with a wide input voltage range of 2.5V to 5.5V. The device is available in a 3.3V fixed output and an adjustable voltage versions. This device is targeted at the portable e with high current re from single-cell Li-Ion batteries. It can operate in the forced continuous pulse width modulation (PWM) mode. The SGM6011 is highly efficient with peak efficiency at 95% when in operation. The device could operate at  duty cycle to achieve the lowest dropout and longer battery life.

This device is capable to provide up to 2A output load current and operates at a 1.4MHz constant frequency to achieve the smallest size of external components. The internal slope compensation allows the use of smaller-value inductors to give improved solution size to this device.

The SGM6011 is available in Green TDFN-3×3-10L package and is rated over the -40℃ to +85℃ temperature range.
