POWER LOSS (W) LTC3122 15V, 2.5A Synchronous Step-Up DC/DC Converter with Output Disconnect Fea T Descrip T n V Range: 1.8V to 5.5V, 500mV After Start-Up The LTC 3122 is a synchronous step-up DC/DC converter IN n Output Voltage Range: 2.2V to 15V with true output disconnect and inrush current limiting. The n 800mA Output Current for V = 5V and V = 12V 2.5A current limit along with the ability to program output IN OUT n Output Disconnects from Input When Shut Down voltages up to 15V makes the LTC3122 well suited for a n Synchronous Rectification: Up to 95% Efficiency variety of demanding applications. Once started, opera- n Inrush Current Limit tion will continue with inputs down to 500mV, extending n Up to 3MHz Adjustable Switching Frequency runtime in many applications. Synchronizable to External Clock The LTC3122 features output disconnect in shutdown, n Selectable Burst Mode Operation: 25A I Q dramatically reducing input power drain and enabling n Output Overvoltage Protection V to completely discharge. Adjustable PWM switching OUT n Soft-Start from 100kHz to 3MHz optimizes applications for highest n <1A I in Shutdown Q efficiency or smallest solution footprint. The oscillator n 12-Lead, 3mm 4mm 0.75mm Thermally can also be synchronized to an external clock for noise Enhanced DFN and MSOP Packages sensitive applications. Selectable Burst Mode operation reduces quiescent current to 25A, ensuring high efficiency a T across the entire load range. An internal soft-start limits inrush current during start-up. n RF Power n Piezo Actuators Other features include a <1A shutdown current and ro- n Small DC Motors bust protection under short-circuit, thermal overload, and n 12V Analog Rail From Battery, 5V, or Backup Capacitor output overvoltage conditions.
