AEM30330 DATASHEET Highly Versatile, Regulated Single-Output, Buck-Boost Ambient
Energy Manager For AC/DC Sources with Optional Primary Battery
Features Description Ultra-low power start-up -Cold start from 275 mV input voltage and 3 µW input power
(typical) Very efficient energy extraction -Open-circuit voltage sensing for Maximum Power Point
Tracking (MPPT)
-Selectable open-circuit voltage ratios from 35% to 80% or
fixed impedance
-Programmable MPPT sensing period
-MPPT voltage operation range from 100 mV to 4.5 V Adaptive and smart energy management with optional
primary battery -Switches automatically between boost, buck-boost and
buck operation, to maximize energy transfer from its input
to the output
-Automatically selects between the source, storage element
and an optional primary battery
-Automatically select the output between the internal
supply, the load and the storage element Load supply voltage -Current drive capability: 30 mA in low power mode, 60 mA
in high power mode
-Selectable load voltage from 1.2 V to 3.3 V Battery protection features -Selectable over-charge and over-discharge protection for
any type of rechargeable battery or (super-)capacitor
-Fast super-capacitor charging
-Dual cell super-capacitor balancing circuit Smallest footprint, smallest BOM -Only four external components are required
-One 10 µH inductor
-Three capacitors: one 10 µF, one 15 µF, one at least 40 µF SOURCE LOUT BUFSRC SRC VINT AEM30330 VINT CINT …
