XCL209 Series DC/DC Converters

Torex Semiconductor's XCL209 series is a synchronous step-down micro DC-DC converter which integrates an inductor and a control IC in one tiny package (2.5 mm x 2.15 mm, h=1.05 mm). A stable power supply with an output current of 400 mA is configured using only two capacitors connected externally. Soft start and on/off functions with CL discharge are provided, and the IC can be put in the standby state by inputting a Low level signal into the CE pin.

An internal coil simplifies the circuit and enables minimization of noise and other operational trouble due to the circuit wiring. The XCL209F083DR provides an externally set output voltage. The XCL209 series achieves high efficiency while holding down output ripple across the full range of loads, from light to heavy, enabling the extension of battery operation time.

  • Easy replacement of LDO for small portable devices that require high efficiency
  • Ultra small configuration (2.5 mm x 2.15 mm, h=1.05 mm) is ideal for the reduction of board mounting area
  • Mobile phones, Smart phones
  • Tablet PCs
  • PND
  • PC peripheral devices
  • DSC, Camcorders
