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-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.
