SGM61030 3A High Efficiency Synchronous Step-Down Converter
●The SGM61030 is a high efficiency and miniature size synchronous step-down converter for low input voltage applications. This high frequency device does not need external compensation and is a perfect solution for compact designs. The 2.5V to 5.5V input voltage range is suitable for almost all available battery chemistries. For the SGM61030A version, to keep the high efficiency in the whole load range, the device operates in pulse width modulation (PW M) mode when the load is not light and automatically enters the power-save mode (PSM) at light loads. For the SGM61030B version, the device operates in continuous current mode (CCM) at light and heavy loads.
●This device employs an adaptive off -time architecture, but still allows a wide range of output capacitors from 22μF to 150μF and even more. This flexibility makes the device a good choice for system power rails supplies. The adaptive off -time architecture provides excellent output voltage accuracy and superb load transient response.
●The SGM61030 is available in a Green TDFN-2×2-7L package and can operate in the -40°C to +125°C ambient temperature range
