DIO6145中文资料5.5V 6A 1.2MHz，同步直流降压转换器数据手册DIOO规格书

描述 Description

The DIO6145 is a step-down DCDC converter with power MOSFETs integrated. It is able to provide a continuous output current of up to 6 A. The output voltage can be regulated as low as 0.6 V. It also offers various protection schemes such as current-limit and thermal shutdown. Optimized COT architecture (Constant on Time) allows both fast transient response and loop stability. Housed in a small flip-chip based QFN2*3-12 and QFN2*1.5-12 package, the DIO6145 requires minimal external components to implement 6 A output capability with superior thermal performance.
