TLV62595 2.5 V to 5.5 V Input 4 A Step-Down Converter

Texas Instruments' converter offers 1% output accuracy in 1.5 mm x 1.5 mm QFN package

Image of Texas Instruments' TLV62595 4 A Step-Down ConverterTexas Instruments' TLV62595 is a high-frequency synchronous step-down converter that is optimized for a compact solution size and high efficiency. The device integrates switches that can deliver an output current up to 4 A. At medium to heavy loads, the converter operates in pulse width modulation (PWM) mode with a 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 TLV62595 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 capacitors. The device is available in a 6-pin 1.5 mm x 1.5 mm QFN package, offering a solution with high power density.
