TPS65290 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...
