Energy Harvesting Employs Low Quiescent Current, Multi-Mode PMIC
A power management integrated circuit (PMIC) handles a lot from microamps to numerous milliamps and can distribute capability to devices employed in a power harvesting system.
The hub of an energy harvesting sensor system is the particular TPS65290 from Texas Tools, a PMIC that provides successful system management with regard to loads ranging from fragments of a microamp to a few 100 miliamps. The IC works over a 2.A couple of V to 5 / input range and incorporates:
1. Manufacturing facility selectable low quiescent current always-on strength supplies, including:
25 mA buck air compressor with 300 nA quiescent current
10 mA LDO along with 400 nA quiescent current
15 mA Zero IDDQdrop together with 100 nA quiescent current
2. 500 mA buck/boost ripping tools employs PFM/PWM operation along with forced PWM option
3. 150 mA reduced dropout regulator
4. Eight electrical power distribution switches utilized to support different configurations for the various loads
