Description

SGM61044L 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 SGM61044L, 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. 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. SGM61044L is available in a Green UTDFN-1.5×1.5-6L package.
