1.2 A, DC-to-DC Inverting Regulator
The input voltage range of 2.85 V to 15 V supports a wide variety of applications. The integrated main switch enables the generation of an adjustable negative output voltage down to 39 V below the input voltage.
The ADP5073 operates at a pin selected 1.2 MHz/2.4 MHz switching frequency. The ADP5073 can synchronize with an external oscillator from 1.0 MHz to 2.6 MHz to ease noise filtering in sensitive applications. The regulator implements programmable slew rate control circuitry for the MOSFET driver stage to reduce electromagnetic interference (EMI).
The ADP5073 includes a fixed internal or resistor programmable soft start timer to prevent inrush current at power-up. During shutdown, the regulator completely disconnects the load from the input supply to provide a true shutdown. A power-good pin is available to indicate the output is stable.
Other key safety features in the ADP5073 include overcurrent protection (OCP), overvoltage protection (OVP), thermal shutdown (TSD), and input undervoltage lockout (UVLO).
The ADP5073 is available in a 16-lead LFCSP and is rated for a −40°C to
- Bipolar amplifiers, ADCs, digital-to-analog converters (DACs), and multiplexers
- High speed converters
- Radio frequency (RF) power amplifier (PA) bias
- Optical modules
This product has been released to the market. The data sheet contains all final specifications and operating conditions. For new designs, ADI recommends utilization of these products.
The ADP5073CP-EVALZ evaluation board is used to demonstrate the functionality of the ADP5073 dc-to-dc converter.
Simple device measurements, such as line regulation, load regulation and efficiency, can be evaluated with the board. Device features, including selectable operating frequency, soft start and slew rate control, may be demonstrated. The board has been designed to show the smallest footprint layout that can be accomplished with this part.
For more details about the dc-to-dc converter, refer to the ADP5073 datasheet.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
