1 / 36 page DM7300G Series Digital Power Manager Data Sheet ZD-00896 Rev. 5.2, 9-Apr-13 www.power-one.com Page 1 of 36 Member of the Family Applications • Low voltage, high density systems utilizing dPwerTM Digital Intermediate Bus Architectures • Broadband, networking, optical, and wireless communications systems • Industrial computing, servers, and storage applications Benefits • Eliminates the need for external power management components • Communicates with the host system via the industry standard I2C communication bus • Reduces board space, system cost, complexity, and time to market Features • RoHS compliant for all six substances • Compatible with both lead-free and standard reflow processes • Programs, controls, and manages up to 32 independent dPOL converters via an industry standard I2C interface (both 100kHz and 400kHz) • JTAG IEEE 1149.1 compliant programming interface • Controls and monitors industry standard power supplies and other peripheral devices (fans, etc) • Programs output voltage, protections, optimal voltage positioning, turn-on and turn-off delays and slew rates, switching frequency, interleave (phase shift), and feedback loop compensation of the dPwerTM POL converters • User friendly GUI interface for programming, monitoring, and performance simulation • Four independent OK lines for flexible fault management and fast fault propagation • Four interrupt inputs with programmable hot swap support capabilities • Intermediate bus voltage monitoring and protection • AC Fail input • Non-volatile system configuration data memory • 1K Byte of user accessible non-volatile memory • Control of industry standard DC-DC front ends • Crowbar output to trigger the optional crowbar protection • Run-time counter • Small footprint semiconductor industry standard QFN64 package: 9x9mm • Wide industrial operating temperature range Description Power-One’s point-of-load converters are recommended for use with regulated bus converters in an Intermediate Bus Architecture (IBA). T he DM7300 is a fully programmable digital power manager that utilizes the industry-standard I2C communication bus interface to control, manage, program and monitor up to 32 dP-series POL converters and 4 independent power devices. The DM7300 completely eliminates the need for external components for power management and programming and monitoring of the dPwerTM POL converters and other industry standard power and peripheral devices. Parameters of the DM7300 are programmable via the I2C bus and can be changed by a user at any time during product development and deployment. |
