The SGM61061 device is a 2.8V to 5.5V synchronous Buck converter with constant off-time architecture that is optimized solution for high efficiency and compact size. The device integrates switches capable of delivering an output current up to 6A.
When MODE input is lower than 0.4V or floating, SGM61061 enters into a pulse frequency modulation (PFM) mode. At medium to heavy loads, the device operates in pulse width modulation (PWM) mode with 1.4MHz (TYP) switching frequency. At light loads, the device automatically enters in power-save mode (PSM) to maintain high efficiency over the entire load current range. When MODE input voltage is more than 1.2V, SGM61061 enters into a pulse width modulation (PWM) mode over the entire load current range. In shutdown state, the current consumption is reduced to 0.5μA (MAX).
The SGM61061 can dynamic regulate output voltage by MODE/VCON pin to meet some situations need change output voltage directly. When MOED/VCON pin get an appropriate voltage value (from 0.6V to 1.1V), SGM61061 will work in PWM mode and internal reference voltage changes smoothly to achieve a new output voltage without changing external resistor divider.
The SGM61061 is available in a Green TQFN-2×3-12L package.
