The TPS61299x/xA is a synchronous boost converter with 95nA ultra-low quiescent current and average input current limit. The device provides a power solution for portable equipment with alkaline battery and coin cell battery. This device has high efficiency under light-load condition to achieve long operation time and average input current limit can avoid battery discharging with high current.

The TPS61299x/xA has wide input voltage range from 0.5V to 5.5V and output voltage range from 1.8V to 5.5V. The device has different versions for average input current limit from 5mA to 1.9A. The TPS61299 with 1.2A current limit can support up to 500mA output current from 3V to 5V conversion and achieve approximately 94% efficiency at 200mA load.

The TPS61299x/xA has optional fast-load transient performance at output voltage is 4.5V, 5V or 5.5V. In fast-load transient, the typical setting time is 8µs when output current transient from 0A to 200mA.

The TPS61299x supports true shutdown function when it is disabled. And TPS61299xA supports force pass through function when it is disabled. Customer could choose either one for specific application.

The TPS61299x/xA offers a very small solution size with 6-ball 1.2mm x 0.8mm WCSP package and 6-pin 1.6mm x 1.6mm SOT563 package.
