MT2496 Description/概述:
MT2496是一个完全集成的,高效的3A同步整流降压转换器。MT2496在一个较宽的输出电流负载范围内高效工作。
该设备提供了两种操作模式,PWM控制和PFM模式切换控制,这允许在更广泛的负载范围内实现高效率。
MT2496需要最少数量的现成的标准外部组件,并可在一个6针SOT23 ROHS兼容包。
The MT2496 is a fully integrated, high– efficiency 3A synchronous rectified step-down converter. The MT2496 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 MT2496 requires a minimum number of readily available standard external components and is available in an 6-pin SOT23 ROHS compliant package.
