SLVS848A – JULY 2009 – REVISED JULY 2009 600-mA, 6-MHz HIGH-EFFICIENCY STEP-DOWN CONVERTER IN CHIP SCALE PACKAGING 23 • 90% Efficiency at 6MHz Operation • 31µA Quiescent Current The TPS6262x device is a high-frequency • Wide V IN Range From 2.3V to 5.5V synchronous step-down dc-dc converter optimized for • 6MHz Regulated Frequency Operation battery-powered portable applications. Intended for low-power applications, the TPS6262x supports up to • Best in Class Load and Line Transient 600mA load current, and allows the use of low cost • ±2% Total DC Voltage Accuracy chip inductor and capacitors. • Automatic PFM/PWM Mode Switching With a wide input voltage range of 2.3V to 5.5V, the • Low Ripple Light-Load PFM Mode device supports applications powered by Li-Ion • Internal Soft Start, 120-µs Start-Up Time batteries with extended voltage range. Different fixed voltage output versions are available from 1.2V to • Integrated Active Power-Down Sequencing 2.3V. (Optional) • Current Overload and Thermal Shutdown The TPS6262x operates at a regulated 6-MHz switching frequency and enters the power-save mode Protection operation at light load currents to maintain high • Three Surface-Mount External Components efficiency over the entire load current range. Required (One MLCC Inductor, Two Ceramic Capacitors) The PFM mode extends the battery life by reducing the quiescent current to 31 µA (typ) during light load • Complete Sub 1-mm Component Profile and standby operation. For noise-sensitive Solution applications, the device can be forced into fixed • Total Solution Size <12 mm2 frequency PWM mode by pulling the MODE pin high. • Available in a 6-Pin NanoFree™ (CSP) In the shutdown mode, the current consumption is reduced to less than 1 µA. Regular and Ultra-Thin Packaging The TPS6262x is available in an 6-pin chip-scale package (CSP). • Cell Phones, Smart-Phones • WLAN, GPS and Bluetooth™ Applications • DTV Tuner Applications • DC/DC Micro Modules Figure 1.
