DESCRIPTION  
TPS65290 is a PMIC designed to operate in applications dependent on efficient power management over a wide  
range of system load conditions ranging from fractions of a microamp to a few hundred miliamps. 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.
