Three logic outputs
from compact regulators
Texas Instruments has developed a pair of triple-output plug-in power solutions that provide three logic-level voltages as low as 1.2V
The modules are designed to provide three regulated low-voltage outputs for mixed logic applications, such as DSPs, ASICs and microprocessors. Both triple-output modules have a 50% smaller footprint than conventional single-output modules, reducing board space and costs. In addition to saving board space, the PT4820 and PT4850 ease design and speed time to market with internal sequencing of all three outputs.

The sequencing meets the power up and power down sequencing requirements of TI's latest DSPs.
The isolated 35W PT4820 and the 75W PT4850 each operate from a 48V input and can provide combinations of 5, 3.3, 2.5, 1.8, 1.5 or 1.2V to power various digital applications including new DSPs, ASICs and microprocessors requiring 1.5 or 1.2V core voltages.
As part of TI's Excalibur series, the PT4820 and PT4850 are available in surface-mount, vertical through-hole or horizontal through-hole styles and offer industry-leading features including: output currents of 8/6/6A (PT4820) and 15/10/10A (PT4850); 1500V input/output isolation; the novel space-saving Excalibur package for better thermal management and flexible mounting options (no heatsinks required); industry-standard protection features, including short-circuit (all outputs), current limit, overtemperature, overvoltage and undervoltage lockout; dual inhibit (on/off); and UL, CSA, IEC, and VDE approvals.
Samples of the PT4820 and PT4850 are available now with volume production planned for May.
Planned pricing in quantities of 1000 is $65 for the PT4820 series and $97 for the PT4850 series.
