TPS60140PWP

The TPS60140PWP is a highly compact and feature-rich power supply solution integrated with a Step-Up/Step-Down Converter, ideal for portable and space-constrained applications. The device integrates an N-channel synchronous Buck-Boost converter with up to 500 mA of output current, and is available in thermally enhanced 10-Lead 2 x 2 mm WSON and 6 x 6 mm QFN packages. This product is designed to automatically and seamlessly switch from the input supply source to a stored charge, simplifying system design and reducing the number of components, size and complexity of the end-product.

The TPS60140PWP application field includes a vast array of products, such as mobile devices such as smartphones, tablets and notebooks, climate control systems, security systems, healthcare, point-of-sale (POS) systems and more. This power supply solution is designed to ensure robust and reliable operation in cost and space-sensitive applications.

The TPS60140PWP works by converting the input power source, which could be either a 5-V or 3-V supply, into a regulated 1.2-V DC voltage. This power is then passed through a synchronous Buck-Boost converter, which can step up or step down the voltage to meet the specified output level. The device can also provide a boost/buck or buck/boost conversion, allowing it to be used as both a step-up and step-down converter.

The TPS60140PWP has a variety of features that make it particularly well-suited for power applications requiring reliable, low-noise and cost-effective performance. It features an integrated N-Channel MOSFET, which reduces losses, and an active low Power Good (PG) pin that provides a delayed enable signal for buck regulator enable control. It also features an internal current limit and short-circuit protection, as well as overvoltage and thermal shutdown protection.

The TPS60140PWP is a cost-effective and reliable choice for power management applications in space-constrained and portable applications. It features a versatile slew-rate control system for performance optimization, along with active low Power Good pin, integrated protection circuitry and low Ri current sensing for enhanced safety. The device also provides automatic changeover between boost and buck modes, further reducing complexity in design and cost.
