Features & Applications

The MCP1603 series of high efficiency fully integrated 500 mA 2.0 MHz synchronous buck regulator ideally suited for Li-Ion/NiMH Battery powered application powered. At heavy loads, the MCP1603 operates in the 2.0 MHz fixed frequency PWM mode which provides a low noise, low output ripple, small-size solution.

When the load is reduced to light levels, the MCP1603 automatically changes operation to a PFM mode to minimize quiescent current draw from the battery. No intervention is necessary for a smooth transition from one mode to another. These two modes of operation allow the MCP1603 to achieve the highest efficiency over the entire operating current range.

Features:

  • Small packages: TSOT-23 and 2x3 DFN
  • PWM/PFM automatic transistion
  • Over current and temperature protection
  • Automatic PWM/PFM mode transition
  • Eff. 90%, Shutdown Current 100 nA
  • Small passives 4.5 microhenry, 4.5 microfarad

Applications:

  • Cellular Telephones
  • Portable Computers
  • Organizers / PDAs
  • USB Powered Devices
  • Digital Cameras
  • Portable Equipment
  • +5 V or +3.3 V Distributed Systems
