About This Product

■Summary

The MPM3811 is a monolithic step-down switch-mode converter with internal power MOSFETs and an inductor. The MPM3811 provides 1A continuous output current with input voltages from 2.3V to 5.5V with excellent load and line regulation. The MPM3811 is ideal for a wide range of applications including high-performance DSPs, wireless power supplies, portable/mobile devices, and other power-saving systems. Output voltage can be adjusted as low as 0.6V. All you need is an input capacitor, an output capacitor, and a feedback (FB) resistor to complete the design. The constant-on-time control (COT) method provides fast transient response, high light-load efficiency, and easy loop stabilization. Protection features include cycle-by-cycle current limit and thermal shutdown. The MPM3811 requires minimal off-the-shelf standard external components and is available in an ultra-small QFN-10 (2mm x 2mm x 1.6mm) package.
