The TPS43331QDAPRQ1 is an integrated circuit (IC) developed and manufactured by Texas Instruments. This IC is designed to provide two high-performance, synchronous switching voltage regulators in a single package. It features auto-tracking dual switching voltage regulators with an 8-pin power QuikDAP package. The TPS43331QDAPRQ1 is designed for use in space-constrained applications that require multiple voltage rails. The circuit can generate two independent output voltages with a wide range of operating parameters including output voltage range, switching frequency, and output current capacity. It also offers a variety of features such as programmable ripple control, current mode control, output over-voltage protection, cycle-by-cycle current limit, and input over-voltage protection. The device also features cycle-by-cycle current limit, input over-voltage protection, and programmable soft start. Additionally, it can support synchronous buck and boost topologies, thereby improving overall efficiency.
