MAX1703 Overview
Key Features
- The device includes a 2A, 75m Ω , N-channel MOSFET switch and a 140mΩ, P-channel synchronous rectifier
- With its internal synchronous rectifier, the MAX1703 delivers up to 5% better efficiency than similar nonsynchronous converters
- It also features a pulse-frequencymodulation (PFM) low-power mode to improve efficiency at light loads, and a 1µA shutdown mode
- It also contains a linear gain block that can be used to build a linear regulator
- For lower-power outputs and a smaller package, refer to the MAX1700/MAX1701
- For dual outputs (step-up plus linear regulator), refer to the MAX1705/MAX1706
- For an on-board analog-to-digital converter, refer to the MAX848/MAX849
- The MAX1703 evaluation kit is available to speed designs
