The ATI2301 is a step-down current-mode, DC-DC converter. At heavy load, it works at the constant frequency PWM mode which has good stability and transient response. To ensure the longest battery life under light load in portable applications, the ATI2301 features a power-saving pulse-skipping modulation (PSM) mode, which reduces quiescent current to save power.

Internal Synchronous Rectifier
Low Quiescent Current: 40μA
Three output current versions:
         300mA(ATI2301A)
         600mA(ATI2301B)
         800mA(ATI2301C)
High Switching Frequency: 1.5MHz
