Product Description

The ADP5070AREZ is a high performance, dual DC to DC switching regulator with independent positive and negative outputs in 20 pin TSSOP package. The integrated main switch in both regulators enables generation of an adjustable positive output voltage up to +39V and negative output voltages down to -39V below input voltage. The ADP5070 operates at a pin selected 1.2MHz/2.4MHz switching frequency. It can synchronize with an external oscillator from 1MHz to 2.6MHz to ease noise filtering in sensitive applications. Both regulators implement programmable slew rate control circuitry for MOSFET driver stage to reduce EMI. The ADP5070 includes 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 true shutdown. This regulator provides overcurrent protection (OCP), overvoltage protection (OVP), thermal shutdown (TSD) and input undervoltage lockout (UVLO).
Wide input voltage range from 2.85V to 15V
Integrated 1A main switch for boost regulator and 0.6A main switch for inverting regulator
Supported by the ADIsimPower tool set
Boost regulator to generate VPOS output and inverting regulator to generate VNEG output
Out of phase operation
Individual precision enable and flexible start-up sequence
Slew rate control for lower system noise
Resistor programmable soft start timer
Optional single ended primary inductor converter (SEPIC) for automatic step-up/step-down
Operating junction temperature range from -40°C to 125°C
ESD (electrostatic discharge) sensitive device. Proper ESD precautions are recommended to avoid performance degradation or loss of functionality.
