CY39C811

*Not recommended for new design due to EOL. (see PTN173701)

The CY39C811 is the highly efficient buck DC/DC converter IC which adopts the all-wave bridge rectifier using the low- dissipation and the comparator system. It achieves the energy harvest solution for the energy source of the high output impedance such as the piezoelectric transducer.
