TPS62827DMQT

The TPS62827DMQT from Texas Instruments is an easy-to-use, synchronous step-down DC/DC converter designed for high efficiency and compact solutions. It features a DCS-Control topology, enabling a fast transient response and high efficiency up to 97%. The device accepts an input voltage range of 2.4V to 5.5V and can deliver up to 4A of output current, with an adjustable output voltage from 0.6V to 4V.

Key electrical specifications include a low operating quiescent current of 4μA, a switching frequency of 2.2MHz, and 1% output voltage accuracy over the full temperature range. The internal power MOSFETs have low resistance (26mΩ and 25mΩ) to minimize conduction losses. The device also includes features such as power-save mode for light load efficiency, 100% duty cycle for lowest dropout, active output discharge, and a power-good output signal.

Packaged in a small 6-pin VSON-HR (1.5mm x 1.5mm) package, the TPS62827DMQT is suitable for space-constrained applications. It operates within an ambient temperature range of -40°C to 125°C (TJ). Protection features include thermal shutdown and hiccup short-circuit protection, ensuring reliable operation in various conditions. This converter is ideal for applications such as solid-state drives, portable electronics, and industrial PCs.
