Analog Devices, Inc. 2 A/1.2 A DC-to-DC Switching Regulator with Independent Positive and Negative Outputs ADP5071ACPZ

Description
Product Details The ADP5071 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 down to −39 V below input voltage. The ADP5071 operates at a pin selected 1.2 MHz/2.4 MHz switching frequency. The ADP5071 can synchronize with an external oscillator from 1.0 MHz to 2.6 MHz to ease noise filtering in sensitive applications. Both regulators implement programmable slew rate control circuitry for the MOSFET driver stage to reduce electromagnetic interference (EMI). Flexible start-up sequencing is provided with the options of manual enable, simultaneous mode, positive supply first, and negative supply first. The ADP5071 includes a fixed internal or resistor programmable soft start timer to prevent inrush current at power-up. During shutdown, both regulators completely disconnect the loads from the input supply to provide a true shutdown. Other key safety features in the ADP5071 include overcurrent protection (OCP), overvoltage protection (OVP), thermal shutdown (TSD), and input undervoltage lockout (UVLO). The ADP5071 is available in a 20-lead LFCSP or in a 20-lead TSSOP and is rated for a −40°C to +125°C junction temperature range. Applications Bipolar amplifiers, ADCs, DACs, and multiplexers Charge-coupled device (CCD) bias supply Optical module supply RF power amplifier (PA) bias
