GENERAL DESCRIPTION
The MT2499A is a fully integrated, high- efficiency 3.5A synchronous rectified step-down converter. The MT2499A operates at high efficiency over a wide output current load range. This device offers two operation modes, PWM control and PFM Mode switching control, which allows a high efficiency over the wider range of the load. The MT2499A requires a minimum number of readily available standard external ponents and is available in an ESOP8 ROHS pliant package.
