275 Watt (50 Amp) Non-Isolated DC-DC Converters
The PTH12040 series non-isolated DC-DC converter complies with the Point-of-Load Alliance (POLA) standard. It offers some of the most advanced POL functions in the industry, including Auto-Track™ sequencing for controlled power-up/power-down of complex semiconductor devices such as DSPs, FPGAs and ASICs, and voltage margining. Standard features include pre-bias startup, programmable input undervoltage lockout, differential remote sense, remote On/Off and auto resetting short-circuit protection.
PTH12040 series converters have an input voltage range of 8 to 14Vdc and an output voltage that can be trimmed from 0.8 to 5.5 Vdc to meet a wide variety of semiconductor power needs. Rated at 275 watts, the converters offer up to 93% efficiency and can deliver up to 50 amps. Available in through-hole horizontal mount and surface-mount versions, they have a small 1 x 2 inch (26.5 x 52 mm) footprint and an installed height of just 0.35 inch (9 mm).
