LTC4079 Energy Harvesting Charger with Buck, Buck-Boost and LDO Supplies

Energy Harvesting Charger with Buck, Buck-Boost and LDO Supplies

The LTC®4079 is a low quiescent current, high voltage linear charger for most battery chemistry types including Li-Ion/Polymer, Lead-Acid or NiMH battery stacks up to 60V. The maximum charge current is adjustable from 10mA to 250mA with an external resistor. The battery charge voltage is set using an external resistor divider.
