3.0/5.5V电压输入G2227RA1U致新同步降压转换

深圳市科瑞芯闽台进口原装3.0/5.5V电压输入G2227RA1U致新同步降压转换



      The G2227 provide a complete power supply solutionfor handsets or data card. It contains 6 dc/dc
converters and 3 LDOs to power each critical blocks of mobile phone, and is optimized for maximum batterylife, featuring a low ground current when in standby mode operation. All channels DC/DC converters
operate at one fixed frequency of 3.0MHz to optimize size, cost, and efficiency. All Synchronous converters
operate at pulse skipping mode at light load. The G2227 features a I2C compatible interface. 

The G2227 is available in TQFN5X5-32 package.
