The TPSM81299 is a synchronous boost module, with inductor and converter both incorporated inside, providing 95nA ultra-low quiescent current and average input current limit. The device provides a power product for portable equipment with alkaline battery and coin cell battery. This device features high efficiency under light-load condition to achieve long operation time and average input current limit avoids battery discharging with high current.

The TPSM81299 has wide input voltage range from 0.5V to 5.5V and output voltage ranges from 1.8V to 5.5V. The device has different versions for average input current limit from 5mA to 1.5A. The TPSM81299 with 1.2A current limit supports up to 600mA output current from 3.6V to 5V conversion and achieve approximately 94% efficiency at 200mA load.

The TPSM81299 has optional fast-load transient performance at output voltage is 4.5V, 5V or 5.5V. In fast-load transient mode, the typical setting time is 8µs when output current transient from 0A to 200mA.

The device supports true shutdown function when it is disabled.

The TPSM81299 offers a very small solution size with 7-pin 3mm x 2.7mm QFN package .
