The MT3101ADER/MT3101BDER is a high efficiency 2Aconstant on time(COT)controlled synchronous step-down converter.It can operate with input voltage from 2.5V to 5.5V and provide output range from 0.6V to input level,thanks to its 100%duty cycle operation.The constant on-time control scheme simplifies loop compensation and offers excellent load transient response.
MT3101ADER/MT3101BDER consumes extremely low 15µA quiescent current hence achieves superior light load efficiency.The high gain error amplifier in the control loop provides excellent load and line regulation.Proprietary adaptive on-time helps MT3101/A/B to achieve nearly constant switching frequency across load range.
MT3101ADER/MT3101BDER has cycle-by-cycle current limit and hiccup mode to protect over-load or short circuit fault conditions.
MT3101ADER/MT3101BDER is available in low profile 6 leads DFN 2mmx2mm packages.
