PTH12040 Series
Not for New Designs
275 W (50 A) Non-Isolated DC-DC Converters
Offering a high 275 W of output power, the PTH12040 series of non-isolated DC-DC converters comply with the Point-of-Load Alliance (POLA) standard, offering such advanced POL functions as Auto-Track™ (a Texas Instruments trademark) sequencing for controlled power-up/power-down of semiconductor devices, such as DSPs, FPGAs, and ASICs as well as voltage margining. Standard features include pre-bias startup, programmable input undervoltage lockout, differential remote sense, remote on/off, and auto-resetting short-circuit protection. The series accepts an input voltage of 8 to 14 VDC and generates a trimmable output voltage of 0.8 to 5.5 VDC delivering up to 50 A and up to 93% efficiency. Through-hole horizontal mount and surface-mount options are available with a 1 x 2-inch (26.5 x 52-mm) footprint and 0.35-inch (9-mm) installed height.
