Both the IR1161L and IR11688S offer 200V direct sensing which eliminates the need for external voltage dividers. The family also features programmable MOT (minimum on time) ensuring reliable operation from no-load to full-load. The low quiescent current capability meets the standby requirements of the new 2016 efficiency standard in the industry.
Together with Infineon’s energy saving OptiMOS and StrongIRFET MOSFETs, this family of SSR ICs provides a simple solution for SMPS while improving the overall efficiency. The IR1161L is targeted for flyback SMPS in chargers and adapters while the IR11688S is targeted for LLC SMPS in televisions, desktops, silver boxes and micro-servers.
