Description

General part information

TPS62684 Series

The TPS62684 is a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications in which high load currents in a very small solution size and height are required. The TPS62684 is optimized for high efficiency and low output voltage ripple, supports up to 1600-mA load current and allows the use of low cost chip inductor and capacitors. With a input voltage range of 3.25V to 5.5V, the device supports applications powered by Li-Ion batteries as well as 5V rails.

The TPS62684 operates at a 5.5-MHz switching frequency with PWM spread spectrum capability. For noise-sensitive applications, this provides a lower noise regulated output, as well as low noise at the input. The device supports a 2.85V fixed output voltage, requiring no external feedback network.

These features, combined with high PSRR and AC load regulation performance, make this device suitable to replace a linear regulator to obtain better power conversion efficiency.
