Texas Instruments TPS62671 500-mA, 6-MHz High-Efficiency Step-Down Converter, Vout=1.8V TPS62671YFDT

The TPS62671YFDT is a high-frequency synchronous step-down DC-DC converter designed for low-power applications, capable of delivering up to 500 mA of output current with a fixed output voltage of 1.8 V. It operates within a wide input voltage range of 2.3 V to 4.8 V, making it suitable for battery-powered devices. The converter features a regulated switching frequency of 6 MHz, which helps achieve high efficiency, typically around 92%. In light-load conditions, the TPS62671YFDT enters power-save mode, reducing quiescent current to approximately 17 OºA, thereby extending battery life. It also includes a PWM spread spectrum capability to minimize output noise, making it appropriate for noise-sensitive applications. The device is packaged in a compact 6-pin DSBGA format, with a maximum height of 0.4 mm, allowing for space-constrained designs. The TPS62671YFDT is suitable for various applications, including cell phones, CMOS camera modules, and embedded power supplies.
