MPM3822C

2.75V-6V, 2A, Ultra-Small and Ultra-Low Noise Power Module

Datasheet EN

概要

The MPM3822C is a synchronous, step-down, power module with an integrated inductor. The MPM3822C achieves 2A of continuous output current from a 2.75V to 6V input voltage range with excellent load and line regulation. The MPM3822C works in forced continuous conduction mode (CCM) and has a voltage ripple less than 10mV with one output capacitor, making it suitable for optical modules, FGPA, ASIC, and other applications requiring low ripple noise. The output voltage can be regulated as low as 0.6V. Only FB resistors, input capacitors, and output capacitors are needed to complete the design.

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

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

The MPM3822C requires a minimal number of readily available, standard, external components and is available in an ultra-small QFN-18 (2.5mmx3.5mmx1.6mm) package.

Evaluation Tools

EVM3822C-RH-00A Evaluation Kit 2A, Synchronous, Step-Down Module Evaluation Board

The EVM3822C-RH-00A is an evaluation board for the MPM3822C, which is a monolithic step-down module converter with built-in power MOSFETs and inductor. The DC/DC module achieves 2A of continuous output current from a 2.7V to 6V input voltage, with excellent load and line regulation. The MPM3822C works into the forced continuous current mode, and has >10mV voltage ripple with one output capacitor, making it suitable for optical module, FGPA, ASIC, and other applications requiring low ripple noise. The output voltage is regulated as low as 0.6V. Only FB resistors and input and output capacitors are needed to compete the design.

The constant-on-time control (COT) scheme provides fast transient repsponse and easy loop stabilization. Fault condition protection includes cycle-by-cycle current limiting and thermal shutdown. The MPM3822C is available in a small, surface-mounted QFN-18 (2.5mmx3.5mmx1.6mm) package.
