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.

TPS61236EVM-676 — TPS61236 大电流升压转换器评估模块

该 EVM 用于评估同步升压转换器 TPS61236,该转换器在 5V VOUT 下具有 3A 的输出电流,而且具有 < 3µA 的超低静态电流和可编程的输出电流限制。该 EVM 也可用于评估固定 5.1V 版本的 TPS61235。在这种情况下,反馈电阻器会移除,器件的 FB 引脚会直接连接到 VOUT 引脚。
