MPM54304 DC/DC Stepdown Power Module

MPS’ quad-output, DC/DC stepdown power module features up to 2 A and 3 A per output

Monolithic Power Systems’ 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 a fast transient response. Its default 1.5 MHz switching frequency greatly reduces the 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 (7 mm x 7 mm x 2 mm) package.
