It is optimized for single cell Li-Ion and Li-polymer battery powered products, in a wide range of power bank, tablet, and other portable devices. The converter integrates 14-mΩ /14-mΩ power switches and is capable of delivering more than 3.5-A output current for 3.3-V to 5-V conversion. The low Rds(on) of the internal power switches enables up to 97% power conversion efficiency. The TPS6123x has two regulation loops, one is the output voltage regulation loop as the normal boost converters have, and the other is the output current regulation loop. An external resistor can be used to program the maximum output current, and once the output current reaches the programmed value, the current loop kicks in to regulate the output current. The TPS6123x can also indicate the load status. These features can simplify system design, eliminate external power path components like a load switch, and achieve much lower system thermal dissipation and improve the total power conversion effectively. The TPS6123x also consumes only 10-µA quiescent current under a light load condition. This low quiescent current together with the load status indication function makes the device very suitable for Always-On applications. For example, for a power bank application, the TPS6123x can remain always on and report load status to the system controller. 8.2 Functional Block Diagram (1) Internal FB resistor divider is implemented in TPS61235P only. |
