High isolation dc-dc converters with 105C operating temperature range
CUI’s 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 1W / 2W 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 standard 7 pin SIP package measuring 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 static protection to 8 kV. The PEM series costs $4.11 (500) through distribution.
