The MPM54304 is a complete power management module that integrates four high-efficiency DC/DC step-down converters, an inductor, and a flexible logic interface. The constant on-time (COT) control mode provides fast transient response for the DC/DC converter. The default switching frequency of 1.5MHz greatly reduces the size of external capacitors. Adequate protection features include undervoltage lockout protection (UVLO), overcurrent protection (OCP), and overtemperature protection.

The output voltage can be preset by an external voltage divider or by a 3 -time programmable MTP (multi-time programmable) e-fuse via the ^I2C bus . The startup/shutdown timing can also be adjusted via the MTP. The MPM54304 minimizes the number of external components and is packaged in a space-saving LGA (7mmx7mmx2mm) package.
