3 Description
The TPS6103x devices provide a power supply solution for products powered by either a one-cell LiIon or Li-polymer, or a two to three-cell alkaline, NiCd or NiMH battery. The converter generates a stable output voltage that is either adjusted by an external resistor divider or fixed internally on the chip. It provides high efficient power conversion and is capable of delivering output currents up to 1 A at 5 V at a supply voltage down to 1.8 V. The implemented boost converter is based on a fixed frequency, pulsewidth- modulation (PWM) controller using a synchronous rectifier to obtain maximum efficiency. At low lo...
