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.

EVM54304-MN-01A Evaluation Kit 4V to 16V Input, Four-Channel Output Power Module with an I2C Interface and MTP Evaluation Board
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
Graphical User Interface (GUI) supported by MPS used to configure and monitor multiple MPS digital power solutions with an I2C Interface
Communication Interface Device USB to I2C/PMBus, included with product evaluation kit or can be purchased separately.
