UWE-12/6-Q12P-C

With dimensions of only 0.9 by 2.3 by 0.38 inches, the UWE series open frame DC-DC converters deliver up to 75 Watts in an industry-standard “eighth-brick” through-hole package. This format can plug directly into quarter-brick pinouts. Several standard fixed-output voltages from 3.3 Vdc to 24 Vdc assure compatibility in embedded equipment, CPU cards and instrument subsystems. The extended 4-to-1 input power range (9-36V) is ideal for battery-powered, telecom or portable applications. Very high efficiency means no fans or temperature deratings in many applications. An optional thermal mounting baseplate extends operation into most conceivable environments.The synchronous rectifier design uses the maximum available duty cycle for greatest ef- fi ciency and low power dissipation with no reverse output conduction. Other features include low on-resistance FET’s, planar magnetics and heavycopper PC boards. These deliver low output noise, tight line/load regulation, stable no-load operation and fast load step response. All units are precision assembled in a highly automated facility with ISOtraceable manufacturing quality standards.Isolation of 2250 Volts (Q48 models) assures safety and fully differential (fl oating) operation for greatest application fl exibility. On-board Sense inputs compensate for line drop errors at high output currents. Outputs are trimmable within ±10% of nominal voltage. The UWE series are functionally complete.A wealth of protection features prevents damage to both the converter and outside circuits. Inputs are protected from undervoltage and outputs feature short circuit protection, overcurrent and excess temperature shut down. Overloads automatically recover using the “hiccup” technique upon fault removal. The UWE is certifi ed to standard safety and EMI/RFI approvals. All units meet RoHS-6 hazardous materials compliance.
