1 Suggested DC/DC Converters

Table 1-1 highlights the latest point-of-load DC/DC converters with integrated MOSFETs that are applicable for hardware accelerator applications from either a 5-V or 12-V input bus. These devices are designed to achieve high-output voltage accuracy, high efficiency, and good thermal performance. Several devices feature a Power Management Bus (PMBus™) with adaptive voltage scaling and margining. PMBus devices integrate telemetry report voltage, current, and temperature information to a host.
