Texas Instruments' family of non-isolated, plug-in power modules provides ultra-fast transient response rates and dramatically reduce the need for output capacitors.
Featuring a tight 1.5 percent output voltage regulation, the point-of-load modules offer increased performance in a smaller footprint for designers of 3G wireless infrastructure, networking and communication systems that use advanced DSPs, FPGAs, ASICs and microprocessors.
Extending TI’s line of PTH devices, the new T2 series of point-of-load modules support step-down DC/DC conversion from a wide 4.5 V to 14 V input with adjustable output voltages down to 0.7 V at output currents up to 50 A.
The modules offer several advanced features to reduce the overall power solution footprint by as much as 50 percent compared to TI’s previous generation devices.
TI's TurboTrans technology allows designers to dynamically tune the modules using a single external resistor to meet a specific transient load requirement. This results in faster transient response with 40 percent less output voltage deviation and a five to eight times reduction in output capacitance. In addition, system stability is enhanced when using ultra-low equivalent series resistance (ESR) polymer tantalum or ceramic capacitors.
T2 modules also incorporate an innovative SmartSync function that allows the designer to synchronize the switching frequencies of multiple T2 devices to maximize power efficiency and minimize electromagnetic interference (EMI).
SmartSync allows the T2 modules to synchronize at different phase angles using external circuits to help balance source loading and minimize input capacitance. The synchronized modules also make EMI filtering easier by eliminating beat frequencies.
Additional features of the T2 modules include TI’s proprietary Auto-Track sequencing technology, which allows multiple modules to power up and down in sequence without external circuitry.
The unique Auto-Track sequencing feature permits non-isolated power modules to track each other or any external control voltage. Meeting 260 degrees C re-flow requirements, the T2 series also provides advanced pre-bias startup capabilities.
T2 power modules are now available in sample quantities and TI is accepting orders for volume production. Pricing per module in quantities of 1,000 begins at $7.90 for the 6 A PTH08T230W and go up to $36.00 for the 50 A PTV08T250W.
