FEATURES
DESCRIPTION
Power-One’s
DP8110G
is an intelligent, fully programmable step-down point-of-load DC-DC converter integrating digital power
conversion and intelligent power management. It works with the DM7300 Series Digital Power Managers (DPM) which
provides for synchronizing all system Power-On-Load regulators, for an elegant, flexible, low noise power system solution.
All key parameters, sequencing, tracking, fault protection, and compensation parameters of the DP8110G are programmable
via Power-One's I
2
C based GUI. All settings can be changed by a user at any time during product development and service.
Once programmed, the DPM remembers all settings and configures the DP8110G through a self-clocking single wire
communication bus. FLASH memory in the DPM allows changes to be made without the need to solder or rewire the regulator.

At negative (sink) output current (bus terminator mode) the efficiency of the DP8110 degrades resulting in increased internal power dissipation and
switching noise. Therefore maximum allowable negative current under specific conditions is lower than the current determined from the de-rating curves
shown in paragraph.
