Texas Instruments TPS54 Step Down SWIFT DC/DC Converters

Texas Instruments TPS54 Step-Down SWIFT DC-DC Converters provide input transient voltage protection that allows the device and the rest of a board to survive potentially damaging voltage spikes. These Texas Instruments DC/DC converters retain low output voltage even with a 60V transient voltage pulse. The high-performance TPS54 DC/DC converter family also provides light load efficiency, low quiescent current (ideal for applications based on TI MSP430 MCUs), a high switching frequency, and a small package size for space-limited designs. These DC-DC converters are a more basic version that provides ease of use, higher currents, and internal compensation.
