US2652SQ Description
The UTC US2652SQ provides a CCM/valley switching mixed mode operation for better efficiency performance. The operation mode stays at CCM at heavy load, and switch to valley switching at light load. The UTC US2652SQ is a high performance current mode PWM controller ideally suited for low standby power.
