The SGM61032 is a high efficiency and miniature size synchronous Buck converter for low input voltage applications. It is a perfect solution for compact designs. The 2.5V to 5.5V input voltage range is suitable for almost all available battery-powered applications. It operates in PWM mode at 1.5MHz (TYP) in the medium to heavy load range and automatically enters or exits the power-save mode (PSM) at light loads to maintain its high efficiency. During shutdown, the quiescent current is 0.02μA (TYP).
This device is based on an adaptive off-time architecture, but still allows a wide range of output capacitors from 10μF to 150μF and even more. This flexibility makes the device a good choice for system power rails supply. It also supports 100% duty cycle operation and enters path-through mode (PTM) when certain conditions are met. At this mode, the quiescent current is reduced to 32μA. The adaptive off-time architecture provides excellent output voltage accuracy and superb load transient response. Only external feedforward compensation capacitor is needed to obtain faster response.
The SGM61032 is available in a Green SOT-563-6 package.
