Power-One’s DP8105 is an intelligent, fully programmable step-down point-of-load DC-DC converter integrating
digital power conversion and intelligent power management. The dPOL is used in conjunction with DM7300 Series
Digital Power Manager (DPM), and completely eliminates the need for external components for output voltage
setting, sequencing, tracking, protection, monitoring, error amplifier compensation and reporting. All performance
parameters of the DP8105 are programmable and managed through Digital Power Manager via the industry-
2
standard I C communication bus and can be changed by a user at any time during product development and
operation. Telemetry data is available in real time and can be accessed over the I²C bus.
