GENERAL DESCRIPTION

The ADP5090 is an integrated boost regulator that converts dc

power from PV cells or TEGs. The device charges storage elements

such as rechargeable Li-Ion batteries, thin film batteries, super

capacitors, and conventional capacitors, and powers up small

electronic devices and battery-free systems.

enables boost shutdown during a low light condition. In addition,

the DIS_SW pin can temporarily shut down the boost regulator

and is RF transmission friendly.

The charging control function of ADP5090 protects rechargeable

energy storage, which is achieved by monitoring the battery

voltage with programmable charging termination voltage and

shutdown discharging voltage. In addition, a programmable

PGOOD flag monitors the SYS voltage.

The ADP5090 provides efficient conversion of the harvested

limited power from a 16 µW to 200 mW range with sub-µW

operation losses. With the internal cold-start circuit, the regulator

can start operating at an input voltage as low as 380 mV. After

cold startup, the regulator is functional at an input voltage range

of 80 mV to 3.3 V.

An optional primary cell battery can be connected and managed

by an integrated power path management control block that

automatically switches the power source from the energy harvester,

rechargeable battery, and primary cell battery.

By sensing the input voltage at the VIN pin, the control loop keeps

the input voltage ripple in a fixed range to maintain stable dc-

to-dc boost conversion. The VIN OCV sensing and programmable

regulation points of the input voltage allow extraction of the

highest possible energy from the PV cell or TEG harvester. A

programmable minimum operation threshold (MINOP)

The ADP5090 is available in a 16-lead, 3 mm × 3 mm LFCSP

and is rated for a −40°C to +125°C junction temperature range.
