Monolithic Power Systems (MPS) MPM3814C Step-Down Power Modules

Monolithic Power Systems (MPS) MPM3814C Step-Down Power Modules are synchronous ultra-small modules with an integrated inductor. These power modules achieve 1A of continuous output current (I_OUT) from a 2.75V to 6V input voltage (V_IN) range, with excellent load and line regulation. The MPM3814C power modules offer up to 92.3% efficiency with 3.3V to 1.8V and 100% duty cycle in dropout. These step-down power modules include protection features such as cycle-by-cycle current limiting, Short-Circuit Protection (SCP) with hiccup mode, and thermal shutdown.

The MPM3814C power modules operate in Forced Continuous Conduction Mode (FCCM) and deliver smaller output voltage ripple, load regulation, and load transient response across the full load range. These power modules are ideal for optical modules, FPGA, ASIC, and other applications that require low ripple noise and a small PCB area.
