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.
