The TPS6123x is a high current, high efficiency synchronous boost converter with constant output current feature for single cell Li-Ion and Li-polymer battery powered products, in a wide range of power bank, tablet, and other portable devices. The IC integrates 14-mΩ/14-mΩ power switches and is capable of delivering up to a 3.5-A output current for 3.3-V to 5-V conversion with up to 97% high efficiency. The device supports a programmable constant output current to control power delivery, so to save power path components and lower total system thermal dissipation effectively.
The device only consumes a 10-µA quiescent current under a light load condition, and can report load status to the system, which make it very suitable for Always-On applications. With the TPS6123x, a simple and flexible system design can be achieved, eliminating external power path components, saving PCB space, and reducing BOM cost.
In shutdown, the output is completely disconnected from the input, and current consumption is reduced to less than 1 µA. Other features like soft start control, reverse current blocking, over voltage protection, and thermal shutdown protection are built-in for system safety.
The devices are available in a 2.5-mm × 2.5-mm VQFN package.

This EVM is used to evaluate the synchronous boost converter TPS61236, which features 3A output current at 5V VOUT, < 3µA ultra-low current and programmable output current limit. The EVM can also be used to evaluate the fixed 5.1V version TPS61235. In this case the feedback resistors are (...)
A power bank is a portable device that can supply USB power using stored energy in its built-in batteries. This reference design demonstrates a circuit based on the TPS61236 for the USB output port of the power-bank. The reference design features a 5V and 2.4A output capability, auto detection of a (...)
