Bel Power Solutions DP8120G 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 DP8120G are programmable via Bel Power Solutions 2 I C based GUI. All settings can be changed by a user at any time during product development and service. Input voltage range: 814 V Once programmed, the DPM remembers all settings Output voltage range: 0.75.5 V at 0 20 A. and configures the DP8120G through a self-clocking Programmable dynamic output voltage single wire communication bus. positioning for better load transient response Choice of 500 kHz switching for highest FLASH memory in the DPM allows changes to be efficiency or 1 MHz for lowest ripple noise. made without the need to solder or rewire the Flexible Fault Response features regulator.
