Analog Devices Introduces The Most Efficient Switching Regulators In Their Class

ADP2384/86 dc-to-dc regulators integrate ultralow on-resistance (44/11 mΩ) power MOSFETs, making them the most efficient 4-A and 6-A solutions for powering processor cores in compact 168mm² solution size.

Analog Devices, Inc. (ADI), introduced the ADP2384 4-A and ADP2386 6-A, 20-V dc-to-dc regulators featuring ultra-high conversion efficiency of greater than 95 percent in a compact 168 mm² solution size. The ADP2384/86 regulators offer a wide input-voltage range of 4.5 V to 20 V and an output range from as low as 0.6 V up to 18 V with 1 percent voltage accuracy. The accurate current limit protection allows the use of smaller inductors, which helps to minimize board space. The ADP2384/86 regulators provide a precision-enable input and a power-good output to allow a simple and reliable start-up sequence.

The ADP2384/86 offer excellent stability and transient response to minimize the output voltage ripple. The switching frequency of the regulators can be synchronized to an external clock to eliminate beat frequencies between regulators. The ADP2384/86 operate over the −40°C to +125°C junction temperature range and are available in compact 4 mm × 4 mm 24-lead LFCSP packages.
