The device operates over a wide 2.2-V to 5-V input-voltage range and incorporates a very low quiescent current always-on power supply, a 500-mA buck/boost converter, a 150-mA low dropout regulator and 8 power distribution switches. The always-on supply features three different factory selectable options: 30mA buck converter with 300-nA quiescent current. 10-mA LDO with 400-nA quiescent current and 10-mA Zero IDDQ drop with 100-nA quiescent current. The buck-boost converter employs PFM/PWM operation with forced PWM option, for maximum overall efficiency. The switches can be used to support different configurations for the various loads supported by the TPS65290. For energy harvesting applications, a programmable input voltage monitor is integrated to allow for connection and disconnection of the different power blocks and switches without the intervention of the master processor. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
