System controller handles six power convertors
The PS-2606 power system controller provides a complete power management solution for up to six nonisolated DC/DC convertors and one intermediate bus
Recording the last 14 power system faults in an integrated EEPROM, the fault log provides quick identification the precise cause of a power system failure during product design or field failure analysis. For high reliability telecomms and high-end server applications, the 48-pin QFP packaged PS-2607 offers digitally configurable power management of up to six nonisolated DC/DC convertors and an intermediate bus.
The EEPROM also supports unlimited reprogrammability of device configuration registers.
With Potentia's Powercentre Designer software, users can configure the controller to handle interlocked power rail sequencing for startup and shutdown, and to set trim values, overvoltage and undervoltage warning and fault thresholds for each power rail.
Power system designs featuring any type and combination of DC/DC convertor are supported by the PS-2607 and can be validated using Potentia's Powercentre Emulation Platform.

Quality management registered without a glitch
Potentia Semiconductor has achieved registration of its quality management system to the ISO9001:2000 standard, following an audit conducted by QMI
The controller's I2C interface makes secondary side power system data available to system-level CPUs, and through its unique PI-Link isolated communications interface, it can also provide voltage, fuse status and fault data from the 48V primary side via Potentia's PS-1000 series power management ICs.
With a separate input dedicated to intermediate bus voltage monitoring, the controller provides the means to determine the health of the bus before initiating startup sequencing.
The controller can also be configured to automatically retry power sequencing following a fault condition.
The PS-2607's four general purpose I/O pins offer additional flexibility and can be allocated as enable inputs, as power status flags or as interrupts for OV/UV warnings, primary side fault indication or primary side shutdown.
The PS-2607 power system controller is priced at US $6.60 each in 10,000 piece quantities.
