Intended for low-power applications, the TPS623xx supports up to Complete 1-mm Component Profile Solution 500-mA load current and allows the use of tiny, low -0.5% / +1.3% PWM DC Voltage Accuracy Over cost chip inductor and capacitors. Temperature The device is ideal for mobile phones and similar 35-ns Minimum On-Time portable applications powered by a single-cell Li-Ion Power-Save Mode Operation at Light Load battery or by 3-cell NiMH/NiCd batteries. With an Currents output voltage range from 5.4 V down to 0.6 V, the Fixed and Adjustable Output Voltage device supports the low-voltage TMS320 DSP family, processors in smart-phones, PDAs as well as Only 86-A Quiescent Current notebooks, and handheld computers. 100% Duty Cycle for Lowest Dropout The TPS62300 operates at 3-MHz fixed switching Synchronizable On the Fly to External frequency and enters the power-save mode operation Clock Signal at light load currents to maintain high efficiency over Integrated Active Power-Down Sequencing the entire load current range. For low noise (TPS6232x only) applications, the device can be forced into fixed frequency PWM mode by pulling the MODE/SYNC Available in a 10-Pin QFN (3 x 3 mm), 8-Pin pin high. The device can also be synchronized to an NanoFree, and NanoStar (CSP) Packaging external clock signal in the range of 3 MHz. In the shutdown mode, the current consumption is reduced APPLICATIONS to less than 1 A. Cell Phones, Smart-Phones The TPS623xx is available in a 10-pin leadless WLAN and Bluetooth Applications package (3 x 3 mm QFN) and an 8-pin chip-scale Micro DC-DC Converter Modules package (CSP).
