MPM3805GQB-25-Z

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 surface mount 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 MPM3805GQB-18-Z is ideal for a wide range of applications including high performance DSPs, FPGAs, PDAs, portable instruments and storage.
