Included in the package are the switching regulator, inductor and input/output capacitors.
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.
5-MHz switching frequency and enters the powersave 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 (typ) 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.
