TI Delivers Highly Efficient, 3-A Plug-in Power Module in Tiny 12 mm x 10 mm Package

Oct 29, 2004

DALLAS (Oct. 21, 2004) -- Texas Instruments today announced a highly integrated point of load power module that supports up to 3-A of output current and is smaller than a standard TO-220 linear regulator. The new plug-in power module eliminates the need for a heat sink, providing up to 94 percent efficiency to support low-voltage point-of-load power requirements of DSPs, FPGAs, ASICs and microcontrollers used in telecommunications, networking equipment, instrumentation and high-end consumer products. See www.ti.com/sc04231.



plug-in module allows operation from either a 3.3-V or 5-V input bus. Leveraging TI's advanced switch-mode DC/DC topology, the module can efficiently convert a 5-V input bus down to 0.9-V with less than 1-W of power dissipation. Power density is an industry leading 160-W per cubic inch. The output voltage can be adjusted to any voltage from 0.9-V to 3.6-V using a single external resistor.

Key Features for PTH04070W:

  • Up to 3-A Output Current at 85ºC 
  • Input Voltage of 3-V to 5.5-V 
  • Wide-Output Voltage Adjust (0.9-V to 3.6-V) 
  • 160 W/in(3) Power Density 
  • Efficiencies up to 94 Percent 
  • On/Off Inhibit Control 
  • Undervoltage Lockout (UVLO) 
  • Output Overcurrent Protection (Nonlatching, Auto-Reset)
  • Overtemperature Protection 
  • Operating Temperature Range of -40°C to +85°C 
  • UL/VDE Approvals 

Packaging, Pricing and Availability

The PTH04070W module comes in a double-sided, horizontal through-hole or surface-mount package that measures 12.3 mm x 10.2 mm x 3.5 mm. The power modules are now available in volume production from TI and its authorized distributors. Pricing per module in quantities of 1,000 is $4.28. Lead (Pb)-free & RoHS-compatible versions will be available in 1Q05. Application notes, reference designs and TI´s Q4 2004 Power Management Selection Guide are available through power.ti.com.
