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.
