The EVHFC0512-S-00A is an evaluation board designed to demonstrate the capabilities of the HFC0512, a fixed-frequency, current-mode controller with internal slope compensation. The HFC0512 is specifically designed for medium-power, offline, flyback, switch-mode power supplies.

The HFC0512 is a highly efficient, green-mode controller. At light loads, the controller maintains the peak current (I_PEAK) and reduces its switching frequency (f_SW) 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 HFC0512 offers frequency jittering to help dissipate energy generated by the conducted noise. The EVHFC0512-S-00A meets EN55022 conducted EMI requirements.

The HFC0512 features an over-power compensation (OPC) function, which reduces the difference between the low line and high line for the over-power protection (OPP) point. In addition, the device features protections such as thermal shutdown, V_CC under-voltage lockout (UVLO), overload protection (OLP), over-voltage protection (OVP), and brownout protection.
