PTH05050 Series

21.6 Watt (6 Amp) Non-Isolated DC-DC Converters

The PTH05050 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. Standard features include pre-bias startup, input undervoltage lockout, remote sense, remote On/Off and auto resetting short-circuit protection.

PTH05050 series converters have an input voltage range of 4.5 to 5.5 Vdc and an output voltage that can be trimmed from 0.8 to 3.6 Vdc to meet a wide variety of semiconductor power needs. Rated at 21.6 watts, the converters offer up to 95% efficiency and can deliver up to 6 amps. Available in through-hole horizontal mount and surface-mount versions, they have a small 0.5 x 0.87 inch (12.7 x 22.1 mm) footprint and an installed height of just 0.33 inch (8.5 mm).
