GENERAL DESCRIPTION

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.
