Using an H-Bridge Transformer Driver to Charge a Supercapacitor

By: Shasta Thomas

摘要 : With its small size and large load (10W) capability, the MAX13256 H-bridge transformer driver is an attractive solution for charging supercapacitors (supercaps). However, a large capacitance on the output of the circuit can force the driver into fault mode at startup, due to the high initial charge current. This application note presents a solution that allows users to charge a large capacitance without going into fault.
