ADP5076 DC-to-DC Switching Regulator

Analog Devices ADP5076 DC-to-DC Switching Regulator generates independently regulated positive and negative rails. The regulator's input voltage range of 2.85V to 5.5V supports various applications. The device is ideal for bipolar amplifiers, analog-to-digital (ADC) converters, digital-to-analog (DAC) converters, multiplexers, and radio-frequency power amplifier bias. The integrated main switch in both regulators enables the generation of an adjustable positive output voltage up to +35V and a negative output voltage as low as −30V. ADP5076 operates at a pin-selected 1.2MHz or 2.4MHz switching frequency. The device also can synchronize with an external oscillator from 1.0MHz to 2.6MHz to ease noise filtering in sensitive applications.
