FEATURES Total Solution Size <6.7 mm 95% Efficiency at 3MHz Operation 23μA Quiescent Current High Duty-Cycle Operation Best in Class Load and Line Transient ±2% Total DC Voltage Accuracy Automatic PFM/PWM Mode Switching Low Ripple Light-Load PFM Mode Excellent AC Load Regulation Internal Soft Start, 200-µs Start-Up Time Integrated Active Power-Down Sequencing (Optional) Current Overload and Thermal Shutdown Protection Sub 1-mm Profile Solution DESCRIPTION The TPS8269x SIP device is a plete 500m A / 800m A, DC/DC step-down power supply intended for low-power applications. Included in the package are the switching regulator, inductor and input/output capacitors. No additional ponents are required to finish the design. The TPS8269x SIP is based on a high-frequency synchronous step-down dc-dc converter optimized for battery-powered portable applications. The Micro SIP™ DC/DC converter operates at a regulated 3-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 23μA (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. These features , bined with high PSRR and AC load regulation performance, make this device suitable to replace a linear regulator to obtain better power conversion efficiency. The TPS8269x SIP is packaged in a pact (2.3mm x 2.9mm) and low profile (1.0mm) BGA package suitable for automated assembly by standard surface mount equipment. 100.0 95.0 - - - - - - - - - - - 2 - - APPLICATIONS - - - LDO Replacement Cell Phones, Smart-Phones Po L Applications TPS82693SIP DC/DC Converter VBAT CI GND ENABLE EN FB MODE MODE SELECTION VIN SW CO L Efficiency (%) 90.0 85.0 VOUT 2.85 V @ 800m A 80.0 75.0 70.0 65.0 60.0 55.0 50.0 0.1 TPS82693 VOUT = 2.85V...
