Description

This small ZETA converter works with input voltages in the range of 6V to 32V. Thank to the ZETA topology, it is able to stabilize the output voltage to 11V, which is inside the input voltage range. A SEPIC converter might be also employed at the expense of higher output ripple voltage.

Features
  • Very low output ripple voltage 0.14% peak-peak, 20MHz BWL
  • It is possible to use a buck evaluation module and modify it into ZETA topology
  • Design retains the advantage of the SEPIC converter and shows well clamped switch node
