MPM3811GG-Z
Overview
The MPM3811GG-Z is a compact, non-isolated point-of-load (PoL) DC-DC power module that integrates a synchronous step-down regulator with a built-in inductor. It operates from an input voltage range of 2.3V to 5.5V and provides a continuous output current of 1A with peak efficiency up to 91%. The ultra-small 2mm x 2mm footprint makes it ideal for space-constrained designs requiring a simplified power stage.
Why Choose This Part
This module eliminates the need for external inductor selection, significantly reducing PCB area and simplifying EMI management. It features a high 2.2MHz switching frequency to allow the use of small ceramic output capacitors while maintaining low ripple. Safety features include cycle-by-cycle over-current protection, hiccup mode short-circuit protection, and thermal shutdown.
Applications
Key Specifications
Getting Started
Designers should place input and output ceramic capacitors as close to the module pins as possible to minimize parasitic inductance. Refer to the MPS DC-DC Designer tool for thermal simulations and efficiency curves at specific Vout settings. For prototyping, ensure the thermal pad is correctly soldered to a large ground plane to manage the heat generated in the 2mm x 2mm package.
