The ADP5070 is a dual high performance dc-to-dc regulator thatgenerates independently regulated positive and negative rails.The input voltage range of 2.85 V to 15 V supports a wide variety ofapplications. The integrated main switch in both regulators enablesgeneration of an adjustable positive output voltage up to +39 Vand a negative output voltage down to −39 V below input voltage.
The ADP5070 operates at a pin selected 1.2 MHz/2.4 MHzswitching frequency. The ADP5070 can synchronize with anexternal oscillator from 1.0 MHz to 2.6 MHz to ease noisefiltering in sensitive applications. Both regulators implementprogrammable slew rate control circuitry for the MOSFETdriver stage to reduce electromagnetic interference (EMI).Flexible start-up sequencing is provided with the options ofmanual enable, simultaneous mode, positive supply first, andnegative supply first.
The ADP5070 includes a fixed internal or resistor programmablesoft start timer to prevent inrush current at power-up. Duringshutdown, both regulators completely disconnect the loads fromthe input supply to provide a true shutdown.
Other key safety features in the ADP5070 include overcurrentprotection (OCP), overvoltage protection (OVP), thermalshutdown (TSD), and input undervoltage lockout (UVLO).The ADP5070 is available in a 20-lead LFCSP or in a 20-leadTSSOP and is rated for a −40°C to +125°C junction temperaturerange.
