DESCRIPTION

The MPM3864 is a fully integrated, highfrequency,

synchronous, rectified, step-down

power module with an internal inductor. This

device is a compact solution that achieves 6A

of continuous output current (IOUT) across a

wide input voltage (VIN) range with excellent

load and line regulation. The MPM3864 has

synchronous mode operation for higher

efficiency across the IOUT load range.

Constant-on-time (COT) control provides very

fast transient response and easy loop design,

as well as very tight output regulation.

Full protection features include short-circuit

protection (SCP), over-current protection (OCP),

under-voltage lockout (UVLO), and thermal

shutdown.

The MPM3864 requires a minimal number of

readily available, standard external components,

and it is available in a space-saving ECLGA-19

(3mmx3mmx1.85mm) package.
