2A, 1.2MHz Synchronous Step-Down DC-to-DC Regulator
The ADP2119/ADP2120 can support input voltages from 2.3V to 5.5V. The output voltage can be adjusted from 0.6V to input voltage (VIN) for the adjustable version, while the fixed output version is available in preset output voltage options of 3.3V, 2.5V, 1.8V, 1.5V ,1.2V and 1.0V. The ADP2119/ADP2120 require minimal external parts and provide a high efficiency solution with their integrated power switches, synchronous rectifier, and internal compensation. Each IC draws less than 3 μA current from the input source when it is disabled. Other key features include under voltage lockout(UVLO), integrated soft start to limit inrush current at startup, overvoltage protection (OVP), over current protection (OCP) and thermal shutdown (TSD).Applications

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 ADP2119/ADP2120 run from input voltages of 2.3 V to 5.5 V and require minimal external components to provide a high efficiency solution with integrated power switch, synchronous rectifier, and internal compensation.
This will create a template email that will request from us the proper blank evaluation board for that ADI part and your application's power parameters.
Note: Some parts have multiple blank boards for high/low current or for different topologies (Boost, SEPIC, SEPIC-Cuk), while other blank boards support multiple ADI parts. This is why it is important to run the design tool with your parameters before making your email request from the tool.
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.
