Product Description

The MPM3811 is a monolithic, step-down, switch-mode converter with built-in, internal power MOSFETs and an inductor. The MPM3811 achieves 1A of continuous output current from a 2.3V to 5.5V input voltage with excellent load and line regulation. The MPM3811 is ideal for a wide range of applications, including high-performance DSPs, wireless power, portable and mobile devices, and other low-power systems. The output voltage can be regulated as low as 0.6V. Only input capacitors, output capacitors, and feedback (FB) resistors are needed to complete the design.

The constant-on-time (COT) control scheme provides fast transient response, high light-­load efficiency, and easy loop stabilization.

Full protection features include cycle-­by-­cycle current limiting and thermal shutdown.

The MPM3811 requires a minimal number of readily available, standard, external components and is available in an ultra-small QFN-10 (2mmx2mmx1.6mm) package.

High Efficiency, 1A, 5.5V, 2.2 MHz Synchronous Step-down Switcher with Integrated Inductor

The MPM3811 is a monolithic step-down switch mode converter with built-in power MOSFETs and inductor. The DC-DC module has a small surface mount 2mm x 2mm QFN package. It achieves 1A continuous output current from a 2.3V to 5.5V input voltage with excellent load and line regulation. The MPM3811 is ideal for a wide range of applications including high performance DSPs, wireless power, portable and mobile Devices, and other low-power systems. The output voltage can be regulated as low as 0.6V. Only input, output capacitors and FB resistors are needed to complete the design.

The Constant-On-time (COT) control scheme provides fast transient response, high efficiency at light­load and easy loop compensation.

The MPM3811 features fault protection functions including cycle­by­cycle current limit and thermal shutdown.

The MPM3811 requires a minimum number of readily available standard external components and is available in an ultra-small QFN10 (2mmx2mmx1.6mm) package.
