GMT G2262-25AU1U ADFN1X1.5-6 21+ 2A, 1.6MHz, COT同步降压转换器

　　General Description

　　The G2262 is a high efficiency synchronous

　　step-down DC/DC converter. G2262 provides an adjustable

　　regulated output voltage from 0.6V to VIN

　　while delivering up to 2A of output current with input

　　voltage from 2.55V to 6V.

　　The Constant-On-Time control scheme in G2262 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 G2262 is available in small ADFN1X1.5-6 and

　　SOT-563 packages.
