The TPS61299 is a synchronous boost converter with 95-nA 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 TPS61299 has wide input voltage range from 0.5 V to 5.5 V and output voltage range from 1.8 V to 5.5 V. The device has different versions for average input current limit from 5 mA to 1.5 A. The TPS61299 with 1.2-A current limit can support up to 500-mA output current from 3-V to 5-V conversion and achieve approximately 94% efficiency at 200-mA load.

The TPS61299 has optional fast-load transient performance at output voltage is 4.5 V, 5 V or 5.5 V. In fast-load transient, the typical setting time is 8 µs when output current transient from 0 A to 200 mA.

The TPS61299 supports optional force pass through or true shutdown function when it is disabled, which is flexible for always-on system.

The TPS61299 offers a very small solution size with 6-ball 1.2-mm x 0.8-mm WCSP package and 6-pin 1.6-mm x 0.6-mm SOT563 package.
