GENERAL DEscriptION
The SGM6014 is a high-efficient monolithic synchronous buck regulator 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 enter pulse frequency modulation (PFM) (low IQ) mode with typically 55μA quiescent current for highest light load efficiency to maximize battery life.
The SGM6014 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.
SGM6014 is available in both adjustable and 3.3V fixed output voltage versions; in the Green TDFN-3×3-10L package. It is rated over the -40℃ to +85℃ temperature range.
