Description

The TLV62585 device 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 up to 3 A. At medium to heavy loads, the converter operates in pulse width modulation (PWM) mode with typical 1.5-MHz switching frequency. At light load, the device 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 2 µA.

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.

The device is available in a 2-mm × 2-mm QFN or 1.6-mm x 1-6-mm SOT563 package.
