PTH05050 Series

Not for New Designs

21.6 W (6 A) Non-Isolated DC-DC Converters

The 21.6 W PTH05050 series non-isolated DC-DC converter offers such advanced Point-of-Load (POL) functions as Auto-Trackā„¢ (a Texas Instruments trademark) sequencing for controlled power-up/power-down of semiconductor devices like DSPs, FPGAs, and ASICs. Delivering up to 6 A output and 95% efficiency, the 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. The series' standard features include pre-bias startup, input undervoltage lockout, remote sense, remote On/Off, auto-resetting short-circuit protection, and compliance with the Point-of-Load Alliance (POLA) standard. Through-hole horizontal mount and surface-mount options are available with a 0.5 x 0.87-inch (12.7 x 22.1 mm) footprint and an installed height of just 0.33 inches (8.5 mm).
