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 equipment with high current requirements 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 100% 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.
