Included in the package are • 23 μA Quiescent Current the switching regulator, inductor and input/output capacitors. No additional components are required to • High Duty-Cycle Operation finish the design. • Best in Class Load and Line Transient The TPS8269xSIP is based on a high-frequency • ±2% Total DC Voltage Accuracy synchronous step-down dc-dc converter optimized for • Automatic PFM/PWM Mode Switching battery-powered portable applications. The • Low Ripple Light-Load PFM Mode MicroSIP™ DC/DC converter operates at a regulated 3-MHz switching frequency and enters the power- • Excellent AC Load Regulation save mode operation at light load currents to maintain • Internal Soft Start, 200-µs Start-Up Time high efficiency over the entire load current range. • Integrated Active Power-Down Sequencing The PFM mode extends the battery life by reducing (Optional) the quiescent current to 23 μA (typ) during light load • Current Overload and Thermal Shutdown operation. For noise-sensitive applications, the device Protection has PWM spread spectrum capability providing a lower noise regulated output, as well as low noise at • Sub 1-mm Profile Solution the input. These features, combined with high PSRR and AC load regulation performance, make this APPLICATIONS device suitable to replace a linear regulator to obtain • LDO Replacement better power conversion efficiency. • Cell Phones, Smart-Phones The TPS8269xSIP is packaged in a compact (2.3mm • PoL Applications x 2.9mm) and low profile (1.0mm) BGA package suitable for automated assembly by standard surface mount equipment.
