致新2A芯片 G2282A31U COT同步降压转换器

　　General Description

　　The G2282 is a monolithic, step-down, switch mode converter with built-in internal power MOSFETs. It achieves 2A continuous output current from a 2.6V to 6.0V input voltage with excellent load and line regulation.

　　The Output voltage can be regulated to as low as 0.6V. At medium to heavy loads, the switching frequency is 2.2MHz. At light load, the device automatically enters PSM to maintain high efficiency.

　　The Constant-On-Time control scheme in G2282 provides fast transient response to be optimized over a wide range of loads and output capacitors. Thermal shutdown and cycle-by-cycle current limiting are used for protection.
