The MT3068NDCR is a 1.5MHz,4A constant 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.
MT3068NDCR 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 MT3068 to achieve nearly constant switching frequency across load range.
MT3068NDCR has cycleby-cycle current limit and hiccup mode to protect over-load or short circuit fault conditions.MT3068 is available in low profile 10 leads DFN 3mm x 3mm packages.
