3 Description
The TPS6109x devices provide a power supply solution for products powered by either a one-cell Li Ion or Li-Polymer, or a two-cell alkaline, Ni Cd or Ni MH battery and required supply currents up to or higher than 1 A. The converter generates a stable output voltage that is either adjusted by an external resistor divider or fixed internally on the chip. It...
