Eighth-brick DC/DC Converters offer 4:1 ultra-wide input voltages

Typical applications for the UWE series include mobile and battery powered devices, test equipment, telecoms and wireless, plus distributed power architectures in markets such as industrial, military & aerospace, networking & wireless telecom and office equipment.



The UWE series provides a choice of fixed output voltages of between 3.3VDC and 24VDC to ensure compatibility in embedded equipment, CPU cards and instrument sub-systems. The eighth-brick industry standard through-hole package has overall dimensions of 22.9mm (0.9in.) x 58.4mm (2.3in.) x 9.1mm (0.36in.) high. Operating temperature range is -40ºC to +85ºC with derating.



The UWE series has a synchronous rectifier design that provides very high efficiency and low power dissipation, allowing the DC/DC Converters to be used without fans or temperature derating in many applications. An optional thermal mounting baseplate is available to allow operation in the most difficult applications and environments.



No reverse conduction allows monotonic start up into pre-biased loads for greatest application flexibility. The UWE series features remote On/Off control, trim, and remote sense functions to provide compensation for line drop errors at high output currents. Extensive self-protection features prevent potential damage to both the converter and outside circuits, including pre-bias operation, input undervoltage, and output short circuit, overcurrent and over temperature protection. Overloads automatically recover using the ‘hiccup’ technique upon fault removal.



The UWE series provides 1500Vdc isolation voltage and is designed to meet UL/EN/IEC 60950-1, CAN/CSA-C22.2 No. 60950-1 safety approvals and complies with the requirements of RoHS-6 and FCC RFI/EMI certification.
