Description

The TPS82671SIPT is a fully integrated low noise step-down power supply Converter Module intended for low-power applications. No additional components are required to finish the design. The TPS8267x is based on a high-frequency synchronous step-down DC-DC converter optimized for battery-powered portable applications. The MicroSiP™ DC/DC converter operates at a regulated 5.5MHz switching frequency and enters the power-save mode operation at light load currents to maintain high efficiency over the entire load current range. The PFM mode extends the battery life by reducing the quiescent current to 17µA during light load operation. For noise-sensitive applications, the device has PWM spread spectrum capability providing a lower noise regulated output, as well as low noise at the input. 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.
