The TLV62595 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 4 A. At medium to heavy loads, the converter operates in pulse width modulation (PWM) mode with typical 2.2-MHz switching frequency. At light load, the device automatically enters Power Save Mode (PSM) to maintain high efficiency over the entire load current range with a quiescent current as low as 10 µA.

Based on the DCS Control topology, the device provides a fast transient response. The internal reference regulates the output voltage down to 0.6 V with a high feedback voltage accuracy of 1% over the junction temperature range of –40°C to 125°C. The entire solution requires a small 470-nH inductor, a single 4.7-µF input capacitor and three 10-µF or single 47-µF output capacitor.

The device is available in a 6-pin 1.5-mm × 1.5-mm QFN package, offering a high power density solution.
