M3 Technology (M3Tek) MT8101 | Demoboard MT8101 Demo Board

Beschreibung

The MT8101 is a 2.3MHz, 1A constant on-time (COT) controlled synchronous step-down converter. It can operate with input voltage from 2.5V to 6V and provide Fixed Output Voltage 0.9V,1.1V, 1.2V and 1.3V. The constant on-time control scheme simplifies loop compensation and offers excellent load transient response. MT8101 consumes extremely low 26µA 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 MT8101 to achieve nearly constant switching frequency across load range. MT8101 has cycle-by-cycle current limit and hiccup mode to protect over-load or short circuit fault conditions.
