TPS40070PWP is a flexible, integrated power supply solution that helps OEMs maximize power system design flexibility in challenging applications. This advanced PMIC allows OEMs to optimize total system cost and design time by replacing multiple components with a single, integrated device. With an optimized layout and a low-dropout linear regulator, TPS40070PWP achieves a maximum efficiency of 93.9% at full load.

The main application field of TPS40070PWP is power management in applications such as industrial IoT, image processing, automotive, and medical. The device includes a single-input, synchronous Buck (step-down) switching controller, one linear regulator, and a wide range of circuit protection features, eliminating the need for multiple components, allowing the customer to save both size and cost in power supply design.

How does the TPS40070PWP work? The Buck switching controller will receive input signals from the customer and regulate the output voltage, by sensing the voltage level of an external resistor connected in series with the output capacitor. The switching controller output is also connected to the linear regulator which is used to provide an adjustable override (AVL) output voltage.

The TPS40070PWP is designed to have excellent light load capabilities and works best in scenarios where the load current is greater than or equal to 200 mA. When the load current is lower than 200 mA, the switching controller will enter a low-power consumption state, called Puppy Mode, thus eliminating the need to keep a Buck converter on constantly (a common power-saving feature found in modern power supplies). To further improve efficiency, the controller provides a Sleep Mode, which automatically shuts down the switching controller and linear regulator when no load is present. Additionally, the device includes an internal 400mA current limit.

The features and functionalities of the TPS40070PWP make it a perfect choice for customers looking for a reliable, highly efficient, and cost-effective power supply for a number of challenging applications. This advanced PMIC provides an integrated solution with a wide range of circuit protection features and adjustable voltage output, allowing the end user to adjust and optimize the power supply design while saving costs. With excellent light load capabilities, the TPS40070PWP performs optimally in a variety of applications.
