10A DC-DC Intelligent dPOL Bel Power Solutions DP7010G 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 DP7010G are programmable via Bel 2 Power Solutions I 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 DP7010G 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. Input voltage range: 8 V - 14 V Output voltage range: 0.7 - 5.5 V at 0 - 10 A Programmable dynamic output voltage positioning for better load transient response Choice of 500 KHz switching for highest efficiency or 1 MHz for lowest ripple noise Flexible fault response features Multiple turn-on/off slew rates and delays Digital filter compensation Synchronous operation with other supplies Real time performance monitoring Small footprint SMT package: 32 x 16 x 7.05 mm GUI based configuration for short development time Approved to the latest edition and amendment of ITE Safety standards, UL/CSA 60950-1 and IEC60950-1 2 DP7010G Stresses in excess of the absolute maximum ratings may cause performance degradation, adversely affect long term reliability, and cause permanent damage to the converter.
