DESCRIPTION

The MPM54524 is an integrated, quad 5A power

module with an I

2C interface. The device offers a

complete power solution with built-in turn-on/-off

sequencing control, configurable soft start (SS),

compensation, and various protection thresholds.

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

(VOUTx) (where x = A, B, C, or D) is adjustable via

the I2C bus or preset via the multiple-time

programmable (MTP) memory. The power-on/-

off sequence is also configurable via the MTP or

can be controlled via the I

2C.

The MPM54524 offers configurable active

voltage positioning (AVP), which generates a

droop voltage (VDROOP). This allows four

channels in parallel with passive current

balancing. In addition, buck regulator A (buck A)

and buck regulator B (buck B) can operate in

parallel for up to 10A in interleaving mode, which

enables 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 MPM54524 requires a minimal number of

external components, and is available in a

compact ECLGA (8mmx8mmx2.9mm) package.
