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. Full protection features include UVLO, OCP, and thermal shutdown.
The output voltage is adjustable through the I2C bus or preset by the three-time programmable MTP (multi-time programmable) e-fuse. The power on/off sequence is also programmable by MTP. The MPM54304 requires a minimal number external components, and is available in a space-saving LGA (7mmx7mmx2mm) package.

EVM54304-MN-00A Evaluation Kit 4V to 16V Input, Quad-Output Power Module with I2C and MTP Evaluation Board
The EVM54304-MN-00A is an evaluation board for the MPM54304, which integrates four highefficiency, step-down DC/DC converters, inductors, and a flexible logic interface.
The evaluation board can deliver 3A max per output (channels 1 and 2) and 2A per output (channels 3 and 4). Channels 1 and 2 can be paralleled to provide up to 6A of current, and channels 3 and 4 can be paralleled to provide up to 4A of current. The MPM54304 employs constant-on-time (COT) control, which provides ultra-fast load transient response.
The output voltage can be adjusted through the I2C bus or preset by the two-time programmable MTP (multi-time programmable) e-fuse. It can also be adjusted by the external divider; in this condition, the soft-start time is the same from each channel. The power-on/power-off sequence is also configurable via the MTP.
The MPM54304 requires a minimal number of external components, and is available in spacesaving LGA (7mmx7mmx2mm) package.
