Monolithic Power Systems HFC0511GS
The HFC0511 is a fixed-frequency, currentmode controller with internal slope compensation specifically designed for medium-power, offline, flyback, switch-mode power supplies. The HFC0511 is a highly efficient green-mode controller. The HFC0511 offers frequency jittering to help dissipate energy generated by the conducted noise.| Part No. | HFC0511GS |

DESCRIPTION
At light loads, the controller freezes the peak current and reduces its switching frequency down to 27kHz to achieve excellent light-load efficiency. At very light loads, the controller enters burst mode to achieve very low standby power consumption. The HFC0511 employs an over-power compensation function to narrow the difference of the over-power protection point between the low line and high line. The HFC0511 also has an X-cap discharge function to discharge the X-capacitor when the input is unplugged. This helps lower the power at no load. Full protection features include thermal shutdown, VCC under-voltage lockout (UVLO), overload protection (OLP), over-voltage protection (OVP), and brown-out protection. The HFC0511 is available in a SOIC8-7A package.FEATURES
