Now stocked by Digi-Key, the STMicroelectronics SPV1050 is an ultra
low-power energy harvester with integrated battery charger designed to help
designers achieve high efficiency and small form factor critical for a
remote sensing node.
The full-bridge DC-DC converter, configurable either in a boost or
buck-boost topology for a wide input voltage range to fit both photovoltaic
(PV) cells or thermal energy generators (TEG), is controlled by a maximum
power point tracking algorithm (MPPT) that can boost the energy harvested by
60%. The SPV1050 is available in a 5mm x 5mm, 20-lead QFN package and in die
form.
