Texas Instruments TLV62585 Step-Down Converter
Texas Instruments TLV62585 Step-Down Converter is a high-frequency synchronous step-down converter optimized for compact solution size and high efficiency. The device integrates switches capable of delivering an output current of up to 3A. The converter operates in pulse width modulation (PWM) mode at medium to heavy loads with a typical 1.5MHz switching frequency. At light load, the Texas Instruments TLV62585 automatically enters Power Save Mode (PSM) to maintain high efficiency over the entire load current range. In shutdown, the current consumption is reduced to less than 2µA. The internal compensation circuit allows a compact solution and small external components. An internal soft start circuit limits the inrush current during startup. Other features like short circuit protection, thermal shutdown protection, output discharge, and Power Good are built-in.Features
