All Rights Reserved. 1 EVHFC0400-S -00A – FULL FEATURES CONTROLLER EV BOARD DESCRIPTION FEATURES HFC0400 is a fixed-frequency current mode controller with built-in slope compensation. At light load condition, it freezes the peak current and reduces its switching frequency down to 25kHz. As a result, it offers excellent efficiency at lightload. At very light load, the controller enters burst mode. So very low standby power consumption can be achieved. • HFC0400 offers frequency jittering which helps to spread out energy in conducted noise. It also has the X-CAP discharge function, through the HV Pin signal motoring, which can decrease the No load consumption further. • • • HFC0400 features variable protections like Thermal Shutdown (TSD), Vcc under Voltage Lockout (UVLO), Over Load Protection (OLP), Over Voltage Protection (OVP), Over Temperature Protection (OTP) and Brown-Out Protection. The HFC0400 is available in the SOIC8-7A package.
