SGM6019 is a high-efficient integrated step-down regulator with 1.2A guaranteed output current. This device is capable to provide an input voltage range of 2.7V to 5.5V, making the use of single-cell Li-Ion battery, three NiMH cells battery or a regulated 5V input possible.

In heavy load condition, this device can work in the forced pulse width modulation (PWM) mode with a switching frequency of 1.6MHz (TYP). In addition, it also can work in the skip mode with 30μA low quiescent current. The 95% high efficiency at light load allows it to be highly efficient to conserve the battery life of devices. Thus, the SGM6019 is specified for the compact devices with low-voltage microprocessor power supply requirements. The SGM6019 also includes the features of internal digital soft-start, peak current limit, short circuit protection and over-temperature protection.

SGM6019 is available in the Green TDFN-2×3-8L package. It is rated over the -40℃ to +85℃ temperature range.
