            MPM3834C 3 A Power Module
                    MPS' MPM3834C low noise power module operates in FCCM and has a small VOUT ripple with one output capacitor
    

MPS' MPM3834C synchronous, step-down power module with an integrated inductor can achieve up to 3 A of continuous output current (I_OUT) across a 2.75 V to 6 V input voltage (V_IN) range with excellent load and line regulation. It operates in forced continuous conduction mode (FCCM) and has a small output voltage (V_OUT) ripple with one output capacitor. This makes the device well-suited for optical modules, FPGA, ASIC, and other applications requiring low ripple noise and a small PCB area.

The V_OUT can be regulated to be as low as 0.6 V. Only feedback (FB) resistors, input capacitors, and output capacitors are required to complete the design. Constant-on-time (COT) control provides a fast transient response, high efficiency, and easy loop stabilization.

Full protection features include cycle-by-cycle current limiting, short-circuit protection (SCP) with hiccup mode, and thermal shutdown.

The MPM3834C requires a minimal number of readily available, standard external components. It is available in an ultra-small ECLGA-14 (2.5 mm x 2.5 mm x 1.2 mm) package.
