The PDQ15-Q48-S5-D is a 15W isolated DC-DC converter designed for applications requiring a regulated power source. It operates over a wide input range of 18 to 75 Vdc, with a nominal input of 48 Vdc, to produce a stable 5 Vdc output at up to 3.0A. This single-output module achieves a typical efficiency of 88% and maintains low output ripple and noise at a maximum of 75 mVp-p. Key features include 1,500 Vdc isolation, remote on/off control, and built-in protections for over-voltage, under-voltage, and short circuits. Its industry-standard 1" x 1" package and wide operating temperature range of -40 to 105°C make it suitable for various industrial and telecommunications systems.
