SG Micro SGM61030

The SGM61030 is a high efficiency and miniature size synchronous Buck 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. This device is based on an adaptive off-time architecture, but still allows a wide range of output capacitors from 22μF to 150μF and even more. The adaptive off-time architecture provides excellent output voltage accuracy and superb load transient response.
