Product Summary

The TPS61220DCKR is a low input voltage step-up converter in 6 pin SC-70 package. It provides a power-supply solution for products powered by either a single-cell, two-cell, or three-cell alkaline, NiCd or NiMH, or one-cell Li-Ion or Li-polymer battery. Possible output currents depend on the input-to-output voltage ratio. The TPS61220DCKR is based on a hysteretic controller topology using synchronous rectification to obtain maximum efficiency at minimal quiescent currents. The output voltage of the adjustable version can be programmed by an external resistor divider, or is set internally to a fixed output voltage. The converter can be switched off by a featured enable pin. While being switched off, battery drain is minimized. The device is offered in a 6-pin SC-70 package (DCK) measuring 2 mm x 2 mm to enable small circuit layout size. The applications of the TPS61220DCKR include Battery Powered Applications, Solar or Fuel Cell Powered Applications, Consumer and Portable Medical Products, Personal Care Products, White or Status LEDs, Smartphones.
