The MT3908 is a fully integrated high efficiency synchronous step-down converter which requires minimum number of external components. It offers very compact solution 8A continuous output current over a wide input range. The MT3908 employs proprietary Constant On-Time (COT) control scheme providing superior transient response and maintainingconstant switching frequency in the continuous conduction mode operation. The external ramp compensation network allows stable operation with ultra-low equivalent series resistance (ESR) output ceramic capacitors. An error amplifier in the control loop provides excellent line and load regulation.The MT3908 integrates extensive protection functions including Input 2.7V under-voltage lockout (UVLO), thermal shutdown, input over-voltage protection (OVP), cycle by cycle current limiting, and short-circuit protection. An open drain power good signal indicates the output within its regulation voltage range. The converter is available in a small 16 pin 3mmx3mm QFN package.
