MPM3814C

2.75V to 6V, 1A, Ultra-Small Power Module

with Ultra-Low Noise

DESCRIPTION

FEATURES

The MPM3814C is synchronous, step-down

power module with an integrated inductor. The

MPM3814C achieves 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 works 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.

•

Wide 2.75V to 6V Operating Input Voltage

(V_IN) Range

Adjustable Output Voltage (V_OUT) from 0.6V

•

Up to 1A Continuous Output Current (I_OUT

100% Duty Cycle in Dropout

Up to 92.3% Efficiency with 3.3V to 1.8V

)

•

Enable (EN) and Power Good (PG) for

Power Sequencing

Cycle-by-Cycle Over-Current Protection

(OCP)

Short-Circuit Protection (SCP) with Hiccup

Mode

Only Four External Components Required

V_OUTcan 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.

Available in an ECLGA-14

(2.5mmx2.5mmx1.2mm) Package

APPLICATIONS

Full protection features include cycle-by-cycle

current limiting, short-circuit protection (SCP)

with hiccup mode, and thermal shutdown.
