The ADP5076 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 5.5 V supports a wide variety of applications. The integrated main switch in both regulators enables generation of an adjustable positive output voltage up to +35 V and a negative output voltage down to ?30 V.?The ADP5076 operates at a pin selected 1.2 MHz or 2.4 MHz switching frequency. The ADP5076 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 metal-oxide semiconductor field effect transistor (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 ADP5076 includes a fixed internal or resistor programmable soft start timer to prevent inrush current at power-up. Other key safety features in the ADP5076 include overcurrent protection (OCP), overvoltage protection (OVP), thermal shutdown (TSD), and input undervoltage lockout (UVLO). The ADP5076 is available in a 20-ball wafer level chip scale package (WLCSP) 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 bias Time of flight module supply
