DESCRIPTION

The MPM3834C is synchronous, step-down

power module with an integrated inductor. The

MPM3834C achieves 3A of continuous output

current (IOUT) from a 2.75V to 6V input voltage

(VIN) range, with excellent load and line

regulation. The MPM3834C works in forced

continuous conduction mode (FCCM) and has a

small output voltage (VOUT) ripple with one

output capacitor. This makes the device wellsuited

for optical modules, FPGA, ASIC, and

other applications requiring low ripple noise and

a small PCB area.

VOUT can be regulated to be as low as 0.6V.

Only FB resistors, input capacitors, and output

capacitors are required to complete the design.

Constant-on-time control (COT) provides 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 (2.5mmx2.5mmx1.2mm) package.
