Texas Instruments Inc. (TI, Dallas, TX) announced six new POLA™, non-isolated, plug-in power modules for telecom and data communications applications that require a low output voltage rail. The new 12 V modules can deliver up to 26 A of output current, and support adjustable output voltages from 0.8 V to 1.8 V with up to 90% power efficiency.
The low-voltage PTH modules feature Auto-Track™ sequencing technology, which simplifies the power-up and power-down of multiple modules. All six devices include a load-fault protection feature by including a non-latching, over-current trip. In addition, a pre-bias startup function prevents the modules from sinking current in applications where an external voltage is present at the module’s output during startup, such as voltage that is fed back through an FPGA or ASIC. To ensure tighter load regulation at higher currents, the 10 A, 12 A, 18 A and 26 A modules include an output-voltage, remote-sense feature.
The new low-voltage PTH modules are available in volume now. The compact devices come in a double-sided, surface-mount construction, and are available in horizontal through-hole or surface-mount styles. Pricing for 1,000-unit quantities is $9.95 for the 6 A modules, $11.50 for the 10 A modules, $13.95 for the 12 A modules, $18.15 for the 18 A modules, and $24.60 for the 26 A modules.
