描述 Description

SGM61044 is a high frequency synchronous Buck converter with an input voltage range from 2.4V to 5.5V and a wide output current range, optimized for compact solutions. For SGM61044A, 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. The minimum static current is only 5.7µA to maintain its high efficiency. For SGM61044B, the device operates in force PWM mode at light and heavy loads. 
With its adaptive hysteresis and pseudo-constant on-time control (AHP-COT) architecture, the load transient performance is excellent and the output voltage regulation accuracy is achieved. 
The device is available in a Green UTDFN-1.5×1.5-6L package.
