ZM7300 controllers are available in industry-standard 9 x 9mm QFN packages that are less than one-sixth the size of Power-One’s previous generation of Digital Power Managers. In addition to purchasing ZM7300 controllers preprogrammed to their exact requirements, customers can perform programming via an IEEE 1149.1 compliant JTAG port during board assembly, or by using the wizard-driven Z-Series graphical user interface and the I2C port.
ZM7300 products also provide “on-the-fly” reprogramming capabilities without having to remove or replace any components on the board. Four independent enable outputs and Power Good inputs facilitate controlling analog components.
Monitoring capabilities include output voltage, current, and temperature for each Z-Series converter. A buffer stores this information for host-system communications, facilitating system-level monitoring and remote diagnostics. Z-Series controllers can also monitor the intermediate voltage bus, accept external interrupts, and initiate crowbar protection.
