MPM3805GQB-25-Z

MPM3805 The Future of Analog IC Technology 6V Input, 0.6A Module Synchronous Step-Down Converter with Integrated Inductor DESCRIPTION FEATURES The MPM3805 is a step-down module converter with built-in power MOSFETs and inductor. The module’s integrated inductor simplifies the power system design and provides easy, efficient use. The DC-DC module comes in a small surfacemount QFN-12 (2.5mmx3.0mmx0.9mm) package and achieves 0.6A continuous output current from a 2.5V to 6V input voltage with excellent load and line regulation. The output voltage is regulated as low as 0.6V. For adjustable output, only FB resistors and input and output capacitors are needed to complete the design. • • • • • • • • • • • The Constant-on-time control (COT) scheme provides fast transient response and eases loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown (TSD). The MPM3805 is ideal for a wide range of applications including high performance DSPs, FPGAs, PDAs, portable instruments and storage. • Wide 2.5V to 6V Operating Input Range Fixed and Adjustable Output from 0.6V QFN-12 (2.5mmx3.0mmx0.9mm) Package Total Solution Size 6mm x 3.8mm Up to 0.6A Output Current 100% Duty Cycle in Dropout Ultra Low IQ: 17μA EN and Power Good for Power Sequencing Cycle-by-Cycle Over-Current Protection Short-Circuit Protection with Hiccup Mode Adjustable Output Only Needs 4 External Components: 2 Ceramic Capacitors and FB Divider Resistors Fixed Output only Needs Input and Output Capacitors APPLICATIONS • • • • • Low Voltage I/O System Power LDO Replacement Power for Portable Products Storage (SSD/HDD) Space-Limited Applications All MPS parts are lead-free and adhere to the RoHS directive.
