PTH08T240F Reduces Output Capacitance by up to 8x, Saving Significant Cost
and Board Space in Point-of-Load System Design
DALLAS, Dec. 4 /Xinhua-PRNewswire/ -- Texas Instruments Incorporated (TI)
(NYSE: TXN) introduced today a 10-A, non-isolated DC/DC power module with
fast transient response and high performance. The plug-in module meets the
strict three percent accuracy core voltage tolerance requirements of TI’s
newest 3-GHz digital signal processors (DSPs), such as the TMS320TCI6487,
with only 3,000 μF of external output capacitance. The device also supports
point-of-load systems that use high-performance DSPs, microprocessors, ASICs
and FPGAs. See: http://www.ti.com/sc06227 .

Based on TI’s extensive T2 family of devices, the new PTH08T240F
incorporates TurboTrans(TM) technology, which optimizes the power module’s
transient response and reduces the amount of output capacitance by up to
eight times. The technology significantly reduces the peak output voltage
deviation under transient load conditions, while saving the customer the cost
and board space for additional capacitors.
The PTH08T240F has a wide input voltage range of 4.5 V to 14 V, and
provides up to 92 percent power efficiency at 1.8-V output. The module’s
output voltage is adjustable from 0.7 V to 2 V, and features over-current
protection and programmable under-voltage lockout. In addition, the
PTH08T240F offers over-temperature protection, on/off inhibit control,
differential remote sense and 1.5 percent DC output regulation.
The module is the first power management device that meets the core
voltage tolerance requirements of TI’s new TCI6487 DSP (see:
http://www.ti.com/tci6487 ). The single chip, multi-core, 3-GHz DSP requires
a core voltage rail between 0.9 V and 1.1 V with a source impedance of 2
milli-ohms. The TCI6487’s voltage tolerance requirement for transient loads
of up to 5 A is only 15 mV, which the PTH08T240F easily supports with only
3,000 μF of external output capacitance. This achievement allows wireless
infrastructure base station OEMs using the new DSP to simplify their power
system designs, while achieving optimal power performance and efficiency.
SmartSync, another element of this module, allows for switching frequency
synchronization of multiple modules, thereby simplifying electromagnetic
interference (EMI) noise suppression tasks and reducing input capacitor
ripple current requirements. The PTH08T240F also includes the Auto-Track(TM)
sequencing feature, which simplifies simultaneous power-up and power-down of
multiple power modules in the system.
Available Today
The PTH08T240F is sampling now and is scheduled to be available in volume
production in early 2007 from TI and its authorized distributors. The module
comes in surface-mount and through-hole packages. Suggested retail pricing
is $11.80 in 1,000-piece quantities. Data sheets, application notes, samples
and TI’s comprehensive portfolio of power management ICs are available
through http://power.ti.com .
