5 Description (continued)

TPS6128xD/E device supports more than 4 A pulsed load current even from a deeply discharged battery. In this

mode of operation, the TPS6128xD/E enables the use of the full battery capacity: A high battery-cut-off voltage

originated by powered components with a high minimum input voltage is overcome; new battery chemistries can

be fully discharged; high current pulses forcing the system into shutdown are buffered by the device seamlessly

transitioning between boost and by-pass mode back and forth.

This has significant impact on the battery on-time and translates into either a longer use-time and better

user-experience at an equal battery capacity or into reduced battery costs at similar use-times.

The TPS6128xD/E offers a small solution size (< 20 mm2) due to minimum amount of external components,

enabling the use of small inductors and input capacitors, available as a 16-pin chip-scale package (CSP).

The TPS6128xD/E operates in synchronous, 2.3 MHz boost mode and enters power-save mode operation

(PFM) at light load currents to maintain high efficiency over the entire load current range.
