HFC0511 Overview
The HFC0511 is a fixed-frequency, currentmode controller with internal slope pensation specifically designed for medium-power, offline, flyback, switch-mode power supplies. The HFC0511 is a highly efficient green-mode controller. At light loads, the controller freezes the peak current and reduces its switching frequency down to 27kHz to achieve excellent light-load efficiency.
