GMT致新 G2275M51U ADFN2X2-73A, 2.4MHz, COT同步降压转换器GMT致新台湾进口原装芯片

　　General Description

　　The G2275 is a monolithic, step-down, switch mode

　　converter with built-in internal power MOSFETs. It

　　achieves 3A 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

　　0.8V. At medium to heavy loads, the switching frequency

　　is 2.4MHz. At light load, the device automatically

　　enters PSM to maintain high efficiency.

　　The Constant-On-Time control scheme in G2275 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.

　　The G2275 is available in a ADFN2X2-7 package.
