The TPS6266x device is a high-frequency synchronous step-down DC-DC converter optimized for battery-powered portable applications. Intended for low-power applications, the TPS6266x supports up to 1000-mA peak load current, and allows the use of low-cost chip inductor and capacitors.
With a wide input voltage range of 2.3 V to 5.5 V, the device supports applications powered by Li-Ion batteries with extended voltage range. Different fixed voltage output versions are available from 1.2 V to 2.3 V.
The TPS6266x operates at a regulated 6-MHz switching frequency and enters the power-save 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 31 µA (typical) during light load and standby operation. For noise-sensitive applications, the device can be forced into fixed frequency PWM mode by pulling the MODE pin high. In the shutdown mode, the current consumption is reduced to less than 1 µA.
The TPS6266x is available in an 6-pin chip scale package (DSBGA).
