Dual output 20-V, 3-A switching regulator features high and flat conversion efficiency

BANGALORE, INDIA: Analog Devices, Inc. (ADI), a global leader in high-performance semiconductors for signal-processing applications, has introduced the ADP2323, a 20-V, 3-A dual output DC-to-DC regulator featuring a high conversion efficiency of greater than 93 percent.

The full featured ADP2323 regulator offers an input voltage supply range of 4.5 V to 20 V and an output range as low as 0.6 V up to 18 V at 1.5 percent voltage accuracy. With more design flexibility and configurability than other DC-to-DC regulators available today, the ADP2323 regulator can be easily configured to synchronize in an evenly phase-shifted topology or for dual-output (2 x 3A) or single interleaved output (up to 6 A).

The ADP2323 provides accurate tracking capability between supplies and includes precision-enable input, voltage tracking input and POWER-GOOD features that allow a simple and reliable start-up sequence.

“For power designers who need higher efficiency more design flexibility and configurability for multi-rail applications, the ADP2323 surpasses other available DC-to-DC regulators,” said Evaldo Miranda, product line director, Power Management Products Group, Analog Devices. “Unlike other regulators, the ADP2323 enables six output rails in an evenly phase-shifted topology, minimizing input current ripple and system interference as well as a power saving mode and current sharing for higher output current capability.”
