By CUI Inc 100
CUI Inc. has introduced a family of low-power board-mount DC-DC converters that provides 3000 VDC I/O isolation and an ultra-wide operating temperature range of -40°C - 105°C for the most demanding applications. The unregulated PEM series is the latest addition to CUI’s second-generation low-power DC-DC converter line and has been specifically designed to improve efficiency and thermal performance in the customer’s application.
The 1 W and 2 W family offers a rugged and reliable solution for converting and isolating DC rails within a range of applications, such as medical, industrial control, security, and telecom systems. The PEM series delivers efficiencies to 89%, a 5% increase over the first-generation. To further enhance the series’ performance across the entire load curve and reduce dissipated heat, the modules have been designed to greatly limit power draw under light and no-load conditions. The PEM family is housed in a compact, industry-standard 7-pin SIP package measuring 0.77 x 0.28 x 0.39 in. (19.6 x 7.0 x 10.0 mm). Nominal inputs of 3.3, 5, 12, 15, and 24 VDC (±10%) and output voltage configurations of 3.3, 5, 9, 12, 15, 24, ±5, ±12, ±15, and ±24 VDC are available. To provide an additional layer of protection for sensitive loads, the PEM family also comes with continuous short-circuit protection and antistatic protection to 8 kV.
