Microenergy Harvesting for Photovoltaic and Thermoelectric
Ultralow Power Regulator for Microenergy Harvesting
Analog Devices introduces ultralow power boost regulators for photovoltaic and thermoelectric energy harvesting systems. The ADP5090 optimizes efficient
conversion of the harvested limited power down to the 15 µW to 1 mW range with best-in-class sub-µW operation losses. Programmable maximum power
point tracking with harvester open circuit voltage sensing ensures that the most energy is extracted from the harvester. The 260 nA quiescent current used
in deep sleep mode prolongs operation time with minimal loss in the absence of ambient energy. Integrated charge pump circuitry enables a cold start at
380 mV input voltage with no energy on the system node.
In addition to efficient ultralow power conversion, ADP5090 provides the best system design flexibility with support of charging different energy storage
through external resistor programmability. An optional backup cell battery can be connected to the ADP5090 that intelligently manages and prioritizes
power paths with fully integrated power switches. ADP5090 is capable of stopping a switcher within 10 μs delay to proceed transmitting data via an RF
transceiver without interference by switching noise.

Analog Devices introduces a new ultralow power regulator,
the ADP5310, which consumes extremely little current
during voltage regulation. It generates superior efficiency,
particularly in ultralight load condition such as sub-1 mW
compared with other dc-to-dc switches. For batterypowered applications where systems need to be always
on but consuming current as low as ten microamps.
Unlike traditional PSM (power saving mode), which still
consumes tens of microamp quiescent current, ADP5310
has only 600 nA I/Q, which enables the efficient conversion
of up to a tens of microamps load.

Moreover, the ADP5310 is equipped with a selectable
forced PWM mode that allows for low noise output voltage
when powering an analog sensitive load. ADP5310 benefits
battery-powered systems with an extended battery life
and offers high efficiency in standby mode and active
mode. The ADP5310 also mitigates noise interference with
analog loads.
