　　The MT3906MFAR is a fully integrated high efficiency synchronous step-down converter which requires minimum number of external components.It offers very compact solution with up to 6A continuous output current over a wide input range.

The MT3906MFAR employs proprietary Constant On-Time(COT)control scheme providing superior transient response and maintaining constant switching frequency under the continuous conduction mode operation.The internal ramp compensation network allows stable operation with ultra-low equivalent series resistance(ESR)output ceramic capacitors without using external compensation network.An error amplifier in the control loop provides excellent line and load regulation.

MT3906MFAR has a MODE pin to select the desirable mode of light load operation.To attain high efficiency at light load,PFM mode and UAM mode could be selected.UAM mode will not allow the part to go below audible frequency(below 25kHz switching frequency).Force PWM mode is also available to support tight output voltage ripple requirement.

The MT3906MFAR integrates extensive protection functions including Input under-voltage lockout(UVLO),thermal shutdown,output overvoltage protection(OVP),cycle by-cycle current limiting,and Hiccup short-circuit protection.An open drain power good signal indicates the output within its regulation voltage range.
The converter is available in small 16 pin 3mmx3mm FC-QFN and 20pin 4mmx4mm QFN package.
