Description

The TPS6256x devices are efficient synchronous step-down dc-dc converters optimized for battery-powered applications. They provide up to 600-mA output current from a single Li-Ion cell and are ideal to power mobile phones and other portable applications.

With a wide input voltage range of 2.5 V to 5.5 V, the devices support applications powered by Li-Ion batteries with extended voltage range, two- and three-cell alkaline batteries, 3.3-V and 5-V input voltage rails. They operate at 2.25-MHz fixed switching frequency and enter power-save mode operation at light load currents to maintain high efficiency over the entire load-current range.

The power-save mode is optimized for low output-voltage ripple. For low-noise applications, the devices can be forced into the fixed-frequency PWM mode by pulling the MODE terminal high. In shutdown mode, the current consumption is reduced to less than 1 µA. Switching at 2.25-MHz allows the use of small inductors and capacitors to achieve a small solution size.

Operating in a forced fixed-frequency PWM mode, the TPS62561 devices allow simple filtering of the switching frequency, e.g., for noise-sensitive applications.

TPS62560 and TPS62562 are available in a 2-mm × 2-mm 6-terminal SON package, whereas TPS62561 is available in a 5-terminal TSOT23 package. Providing a fixed-output-voltage version, this TPS62562 enables a even smaller solution size with no external resistors needed.
