The SGM61061S device is a 2.7V to 5.5V synchronous Buck converter with AHP-COT architecture that is an optimized solution for high efficiency and compact size. The device integrates switches capable of delivering an output current up to 8A.
When MODE input voltage is lower than 0.4V or floating, SGM61061S enters into power-save-mode (PSM) mode. At medium to heavy loads, it operates in pulse width modulation (PWM) state with 1.2MHz (TYP) switching frequency. At light loads, the device automatically enters in pulse frequency modulation (PFM) state to maintain high efficiency over the entire load current range. When MODE input voltage is more than 1.2V, SGM61061S enters into a forced pulse width modulation (FPWM) mode over the entire load current range. In shutdown state, the current consumption is reduced to 0.03μA (TYP).
The SGM61061S is available in a Green TQFN- 2×3-12L package.
