DESCRIPTION

The MPM54313 is a triple 3A, fully integrated

power module with an I

2C interface. The

MPM54313 offers a complete power solution

with built-in power-on/-off sequencing control,

configurable soft start, compensation, and

various protection thresholds.

Constant-on-time (COT) control provides ultrafast transient response. The output voltage (VOUT)

can be adjusted via the I2C bus or preset by the

multiple-time programmable (MTP) memory.

The power on/off sequence is also configurable

via the MTP, or it can be controlled via the I

2C

bus online.

The device offers configurable active voltage

positioning (AVP), which generates a droop

voltage that allows up to three outputs to be

paralleled with passive current balancing. In

addition, buck A and buck B can operate in

parallel for up to 6A in interleaving mode, which

allows for active current balancing.

Full protection features include under-voltage

lockout (UVLO), over-current protection (OCP),

over-voltage protection (OVP), under-voltage

protection (UVP), and thermal shutdown.

The MPM54313 requires a minimal number

external components, and it is available in a

compact BGA (8mmx9mmx2.58mm) package.
