IRS279524STRPBF

The IRS279524STRPBF is a self oscillating Half-Bridge Driver IC for DC-DC resonant converter applications, especially the LLC resonant half-bridge converter. The resonant half-bridge converter control IC has 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. Simple primary-side control solution for fixed and variable frequency DC-DC resonant converters.

• Programmable minimum and maximum switching frequency
• Programmable soft start frequency and soft start time
• Programmable dead time
• Micropower start-up and ultra low quiescent current
• Over-current protection using low-side MOSFET Rds(ON)
• User initiated micropower sleep mode
• Under-voltage lockout
• Simple design with minimal component count
