They employ an interleaved, synchronous-rectifier topology that exploits 100% of their duty cycle. They simultane- ously achieve ultra-high efficiency, tight line/load regulation, low noise, and quick step response. A state of the art, single-board, open-frame design with reduced component count, high efficiency, low-on-resistance FET’s, and planar magnetics embedded in heavy-copper pc boards all contribute to impressive thermal derating. The UQQ’s feature set includes high isolation, input pi filters, input undervoltage shutdown, output overvoltage protection, current limiting, short-circuit protection and thermal shutdown. The standard footprint carries on/off control (positive or negative polarity), output trim (+10/–20%) and output sense functions. All UQQ quarter-bricks are designed with full magnetic and optical isolation up to 2250 Volts DC (basic insulation). For applications requiring wide range input, improved electrical and thermal perfomance consider Murata Power Solutions’ new UQQ Series “Quarter-Brick” DC-DC Converters. They measure just 1.45 x 2.22 x 0.43 inches (36.8 x 56.4 x 10.92mm) and fit the industry- standard footprint. PRODUCT OVERVIEW Typical unit Typical topology is shown. Figure 1. Connection Diagram |
