POL Converters Achieve High Voltage Accuracy

Sixteen new non-isolated, point-of-load, dc/dc converters have been designed to address the voltage and current requirements of high-performance FPGAs, ASICs, DSPs and microprocessors. The NNL10 series converters, with full load current outputs of 10A and high precision voltages ranging from 0.9V to 3.3V, are suited for applications ranging from servers to telecommunications equipment. The converters can operate with a voltage input range of 3.0V to 5.5V and come with output voltages of 0.9V, 1.0V, 1.2V, 1.5V, 1.8V, 2.0V, 2.5V, and 3.3V. Each variant comes with an optional DC OK single wire connection. This connection significantly simplifies output sequencing by indicating when the next converter in a daisy-chained sequence can be enabled. Available in SMD format, the NNL10 converter has an industry-standard footprint suitable for both new and existing designs. Features include continuous short circuit protection, under-voltage lockout, and over temperature protection. Output voltage trimming lets designers adjust the voltage by ±10 percent of nominal by connection of a resistor or by applying a voltage to the converter's trim pin. The device is rated for maximum line and load regulation of 1.0% and 0.55%, respectively, and offers a typical voltage set point accuracy of 1.0%. Footprint is 33.0 mm x 13.5 mm, and maximum board-mounting profile is 8.3 mm. C&D TECHNOLOGIES INC., Tucson, AZ. (800) 547-2537.
