ADP5070 - Analog Devices

ADP5070 DC-to-DC Switching Regulator

The ADP5070 is a dual high performance dc-to-dc regulator that generates independently regulated positive and negative rails. The input voltage range of 2.85 V to 15 V supports a wide variety of applications. The integrated main switch in both regulators enables generation of an adjustable positive output voltage up to +39 V and a negative output voltage d.
