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