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. For the SGM61040A version, to keep the high efficiency in the whole load range, the device operates in pulse width modulation (PWM) mode at normal load and automatically enters the power-save mode (PSM) at light loads. For the SGM61040B version, the device operates in continuous current mode (CCM) at light and heavy loads.
This device is based on adaptive off-time architecture, but still allows a wide range of output capacitors up 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 SGM61040 is available in a Green TDFN-2×2-7L package.
