IR3623MPBF

Data Sheet No.PD94717 revC www.DataSheet4U.com IR3623MPbF HIGH FREQUENCY 2-PHASE, SINGLE OR DUAL OUTPUT SYNCHRONOUS STEP DOWN CONTROLLER WITH OUTPUT TRACKING AND SEQUENCING Description Features 12V Dual Synchronous Controller with 180o Out of Phase Operation Configurable to 2-Independent Outputs or Current Share Single Output Output Voltage Tracking Power up /down Sequencing Current Sharing Using Inductor’s DCR +/-1% Accurate Reference Voltage Programmable Switching Frequency up 1200kHz Programmable Over Current Protection Hiccup Current Limit Using MOSFET RDS(on) sensing Latched Overvoltage Protection Dual Programmable Soft-Starts Enable Pre-Bias Start-up Dual Power Good Outputs On Board Regulator External Frequency Synchronization Thermal Protection 32-Lead MLPQ Package Embedded Telecom Systems Distributed Point of Load Power Architectures Computing Peripheral Voltage Regulator Graphics Card General DC/DC Converters The IR3623 IC integrates a dual synchronous Buck controller, along with IP2003A it is providing a high performance and flexible solution. The IR3623 can be configured as 2-independent outputs or as current share single output. The current share configuration is ideal for high current applications. IR3623 enables output tracking and sequencing of multiple rails in either ratiometric or simultaneous fashion. The IR3623 features 180o out of phase operation which reduces the required input/output capacitance and resu...
