LTC3883IUH#WPBF

LTC3883 is a single phase step-down DC/DC controller with digital power system management. The controller use a constant frequency, current mode architecture that is supported by the LTPowerPlay™ software development tool with graphical user interface (GUI). Switching frequency, output voltage, and device address can be programmed using external configuration resistors. Additionally, parameters can be set via the digital interface or stored in on-chip EEPROM. This device can be configured for Burst Mode® operation, discontinuous (pulse-skipping) mode or continuous inductor current mode. It is widely used in application such as high current distributed power systems, telecom systems, intelligent energy efficient power regulation etc.
