The MPM54304 is a complete power management module that integrates four high-efficiency, step-down DC/DC converters, inductors, and a flexible logic interface. This COT control DC/DC converter provides fast transient response. Its default 1.5MHz switching frequency greatly reduces external capacitor size. The output voltage is adjustable through the I2C bus or preset by the three-time programmable MTP (multiple-time programmable) e-fuse. The power-on/off sequence is also programmable via the MTP.
Full protection features include UVLO, OCP, and thermal shutdown. The MPM54304 requires a minimal number of external components, and is available in a space-saving LGA (7mmx7mmx2mm) package.

The EVM54304-MN-01A is an evaluation board designed to demonstrate the capabilities of the MPM54304, a four-channel output power module with an I2C interface. Channels 1 and 2 can deliver up to 3A (or a shared 6A) of continuous output current. Channels 3 and 4 can deliver up to 2A (or a shared 4A) of continuous output current.
The MPM54304 integrates four high-efficiency, step-down DC/DC converters, four inductors, and an I2C interface. Channels 1 and 2 can be paralleled to provide up to 6A of output current. Channels 3 and 4 can be paralleled to provide up to 4A of output current.
The MPM54304 features constant-on-time (COT) control to provide a fast load transient response. The output voltage (VOUT) can be configured via the I2C bus or preset two times by the multiple-time programmable (MTP) e-fuse. VOUT can also be adjusted via the external resistor divider. When VOUT is set via the resistor divider, each channel’s soft-start time is the same.
The startup and shutdown sequences are configurable via the MTP. The MPM54304 requires a minimal number of external components and is available in a space-saving LGA (7mmx7mmx2mm) package
