MP3410 1.3A, 550kHz Synchronous Rectified Step-up Converter The Future of Analog IC Technology FEATURES DESCRIPTION Over 90% Efficiency The MP3410 is a highly efficient, synchronous, Output to Input Disconnect at Shutdown Mode fixed frequency, current-mode step-up converter with output to input disconnect, inrush current Internal Synchronous Rectifier limiting and internal soft-start. It includes an error Inrush Current Limiting and Internal Soft-Start amplifier, ramp generator, comparator, N-Channel Internal Compensation switch and P-Channel synchronous rectified 1.3A Typical Switch Current Limit switch (which greatly improves efficiency). The 550kHz Fixed Switching Frequency output disconnect feature allows the output to be Zero Current Shutdown Mode completely isolated from the input in shutdown Thermal Shutdown mode. 5-Pin TSOT-23 Package The 550kHz switching frequency allows for APPLICATIONS smaller external components producing a MP3 Players compact solution for a wide range of load currents. The internal compensation and soft-start Handheld Computers and PDAs minimizes the external component count and Digital Still and Video Cameras limits the inrush current during startup. The External Modems MP3410 has integrated power MOSFET which Small LCD Displays can support up to 6V output and typical 1.3A For MPS green status, please visit MPS website under Quality Assurance. switch current.
