HFC0500 Fixed Frequency Flyback Controller with Ultra-low No Load Power Consumption The Future of Analog IC Technology DESCRIPTION HFC0500 is a fixed-frequency current-mode controller with internal slope compensation. It is specifically designed for the medium-power, offline, flyback, switch-mode power supplies. HFC0500 is a green-mode highly efficient controller. At light loads, the controller freezes the peak current and reduces its switching frequency down to 25kHz to offer excellent light-load efficiency. At very light loads, the controller enters burst mode to achieve very low standby power consumption. HFC0500 offers frequency jittering to help dissipate energy generated by conducted noise.
