The TPS2560A and TPS2561A are dual-channel power-distribution switches intended for applications where precision current limiting is required or heavy capacitive loads and short circuits are encountered. These devices offer a programmable current-limit threshold between 250 mA and 2.8 A (typ) per channel via an external resistor. The power-switch rise and fall times are controlled to minimize current surges during turn on/off.
Each channel of the TPS2560A/61A devices limits the output current to a safe level by switching into a constant-current mode when the output load exceeds the current-limit threshold. The FAULTx logic output for each channel independently asserts low during overcurrent and over temperature conditions.

The TPS2560EVM-424 and TPS2561EVM-424 are evaluation modules (EVM) for Texas Instruments power-distribution switches with adjustable current-limit. These EVMs operate over a 2.5-V to 6.5-V range. An on-board jumper sets the output current-limit to either 0.5 A or 1 A. The board is designed for the (...)
This reference design is capable of charging two devices at 2.5A each with over 82% efficiency. The UCC24610 synchronous rectifier controller and CSD17312Q5 FET reduce the rectifier loss and provide high efficiency with a minimal increase in cost. The TPS2561A provides accurate and independent (...)
BQ24745 is a host controlled synchronous buck battery charger capable of charging batteries at up to 19.2V and up to 8 A normally, extended to 10 A with use of 8 mOhm battery sense resistor. The power train is capable of 8 A with convection only cooling and 10 A with moderate fan cooling (~200 (...)
