Description
The IRS2795(1,2) is a self oscillating half-bridge driver IC for DC-DC resonant converter applications,
especially the LLC resonant half-bridge converter. The frequency and dead time can be programmed
externally using two external components. The IC offers over current protection using the on state resistance
of the low-side MOSFET. The IC can be disabled by externally pulling the voltage at the CT/SD pin below its
enable voltage threshold.
