GENERAL DESCRIPTION  
The ADP5070 is a dual high performance dc-to-dc regulator that  
generates independently regulated positive and negative rails.  
The ADP5070 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.  
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.  
Other key safety features in the ADP5070 include overcurrent  
protection (OCP), overvoltage protection (OVP), thermal  
shutdown (TSD), and input undervoltage lockout (UVLO).  
The ADP5070 operates at a pin selected 1.2 MHz/2.4 MHz  
switching frequency. The ADP5070 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).  
The ADP5070 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.
