POLA compatible SIP power modules
15 June 2005
Power Electronics / Power Management
Two new families of POLA (point-of-load alliance) compatible, non-isolated, plug-in power modules are being offered by Texas Instruments. Available in single in-line pin (SIP) packages, the flexible 8 A and 18 A point-of-load power modules support input voltages of 3,3 V, 5 V and 12 V. Additionally, the modules simplify power design in multivoltage systems that use high-speed microprocessors, FPGAs, ASICs and DSPs in an intermediate bus power architecture.
The 8-pin SIP footprint of the PTVxx010 family of DC-DC converters minimises board space. This family provides step-down conversion to a wide range of output voltages, at up to 8 A of output current. The output voltage can be set any value between 0,8 V to 1,8 V, 2,5 V or 3,6 V, depending upon the device's input voltage.
The 12-pin SIP modules, the PTVxx020 family, supports similar systems requiring output currents of up to 18 A.
Both families include Auto-Track sequencing technology to simplify the task of supply-voltage sequencing in a power system.
POLA member companies offer customers advanced, non-isolated modules with the same footprint and form factor. POLA parts are also ensured to be interoperable.
