Texas Instruments  TPS82698SIPR

The TPS8269xSIP device is a complete 500 mA / 800 mA, DC/DC step-down power supplyintended for low-power applications. Included in the package are the switching regulator, inductorand input/output capacitors. No additional components are required to finish the design. TheTPS8269xSIP is based on a high-frequency synchronous step-down dc-dc converter optimized forbattery-powered portable applications. The MicroSIP™ DC/DC converter operates at a regulated 3-MHzswitching frequency and enters the power-save mode operation at light load currents to maintainhigh efficiency over the entire load current range. The PFM mode extends the battery life byreducing the quiescent current to 23 µA (typical) during light load operation. For noise-sensitiveapplications, the device has PWM spread spectrum capability providing a lower noise regulatedoutput, as well as low noise at the input. These features, combined with high PSRR and AC loadregulation performance, make this device suitable to replace a linear regulator to obtain betterpower conversion efficiency. The TPS8269xSIP is packaged in a compact (2.9 mm × 2.3 mm) and lowprofile (1 mm) BGA package suitable for automated assembly by standard surface mountequipment.
