BWR-5/3-3.3/4.25-D12A中文资料Dual Output Mixed Voltage, BWR Models5V and 3.3V, Independent Dual Output 30 Watt, DC/DC Converters数据手册Datel规格书

描述 Description

DATEL's BWR series of DC/DC converters now includes two independent converters in one 2\" x 2\" package. The BWR-5/3-3.3/4.25 family provides both 5V at 3 Amps and 3.3V at 4.25 Amps for a combined output power of 30 Watts from input ranges of 10V to 18V (-D12A), 18 to 36V (-D24A), or 36 to 75V (-D48A).
Each output is regulated by its own control loop to provide ±1% load and ±0.5% line regulation. Individual trim pins and a negative or positive on/off control pin allow independent adjustment of output voltages and any combination of power-on sequencing between the 5V and 3.3V outputs. A high effi ciency of 88% allows full load operation up to +65°C ambient temperature in a still air environment. Although functionally independent, both outputs are driven from synchronized PWMs to prevent asynchronously generated beat frequencies.
