Analog Devices Inc. ADP5072 Dual DC-to-DC Switching Regulator

Analog Devices ADP5072 Dual DC-to-DC Switching Regulator is a high-performance DC-to-DC regulator that generates independently regulated positive and negative rails. The input voltage range of 2.85V to 5.5V supports a wide variety of applications. The integrated main switch in both regulators enables the generation of an adjustable positive output voltage up to 35V and a negative output voltage down to -30V.
