Ricoh Electronic Devices has one-chip solutions: PMU (Power Management Unit) for Xilinx Zynq®-7000 SoC which is popular in industrial applications like programmable logic controllers.

The RN5T568 contains 4 step-down DC/DC converters, 7 LDO regulators, 4 reset ICs, a power control circuit, I²C bass interface, GPIO and thermal shutdown. Meeting the requirements of the SoC by a single chip, the RN5T568 is useful to reduce the development time and cost of applications and mounting area. In addition, high efficiency DC/DC converters and low noise LDO regulators can reduce supply current and enhance accuracy of the system.

In the case power source is DC 24 V or DC 12 V, please use step-down DC/DC converter whose MAX input voltage is 30 V or 34 V together.
