The ATI2305 is a 1.5MHz switching frequency step-down current-mode, DC-DC converter. With excellent stability and transient response, the constant-frequency PWM control works well at heavy load. There is a power-saving Pulse-Skipping Modulation (PSM) mode in the ATI 2305 which can reduce quiescent current under light load operation to save power and ensure the longest battery life in portable applications.
