Isolated DC/DC converters offer high efficiency in rugged, encapsulated package

CUI has extended its line-up of isolated DC/DC converters with the introduction of three new encapsulated models ranging from 10W to 30W.

The PDQ10‑D, PDQ15‑D and PDQ30‑D output 10W, 15W and 30W of power respectively in an industry standard 1 x 1in package, making them suitable as replacements for larger 1 x 2in modules. The PDQ‑D models feature a 4:1 input voltage range of 9 to 36 or 18 to 75V DC with high typical efficiencies up to 90%.

Housed in a compact, low-profile DIP package with a five-sided, shielded metal case, the rugged, encapsulated modules come with single regulated output voltages of 3.3, 5, 12 and 15V DC or dual regulated output voltages of ±5, ±12 and ±15V DC.

The converters offer a wide operating temperature range of -40 to 105°C and with their encapsulated design, the PDQ‑D series is suitable for convection-cooled equipment and harsh environments with target applications that include telecom, industrial, remote sensor systems and portable electronics.

All PDQ-D models offer an input to output isolation of 1,500V DC and feature remote on/off control while single output models also offer output voltage trimming that allows for a ±10% adjustment of the nominal output. Protections for over voltage, input under voltage lockout and continuous short circuit are also included.
