Bel Power Solutions 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 2 programmable via Bel 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 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. Output voltage range: 0.7 V5.5 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 GUI based configuration for short development time. Industry standard size through-hole single-in-line package: 30.7 x 25.3 x 6.00 mm (1.2 x 1.0 x 0.24 in) Approved to the latest edition and amendment of ITE Safety standards, UL/CSA 60950-1 and IEC60950-1 DP8110G 2 1. ABSOLUTE MAXIMUM RATINGS Stresses in excess of the absolute maximum ratings may cause performance degradation, adversely affect long- term reliability and cause permanent damage to the converter.
