96% EFFICIENT SYNCHRONOUS BOOST CONVERTER WITH 4A SWITCH
96% Efficient Synchronous Boost Converter
The TPS6103x devices provide a power supply
With 1000-mA Output Current From 1.8-V
solution for products powered by either a one-cell
Input
Li-Ion 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
