EVHF500-30-P-00A Evaluation Kit HF500-30 Full Featured Flyback Regulator Evaluation Board with Universal Input, 12V/2.5A Output
The HF500-30 is a fixed-frequency, current-mode regulator with built-in slope compensation. It combines a 700V MOSFET and a full-featured controller into one chip for a low-power, offline, flyback, switch-mode power supply.
At medium and heavy loads, the regulator works in a fixed frequency with frequency jittering. Jitterring helps reduce the EMI energy on switching frequency and its harmonics. During a light-load condition, the regulator freezes the peak current and reduces its switching frequency to fOSC(min) to offer excellent efficiency. At very light load, the regulator enters burst mode to achieve low standby power consumption.
HF500-30 is equipped with full protection features, include: brown-in and brownout, VCC under-voltage lockout (UVLO), overload protection (OLP), short-circuit protection (SCP), input over voltage protection, VCC over-voltage protection (OVP), and over-temperature protection (OTP).
The HF500-30 features over-power line compensation to ensure that the overload protection point is independent of the input voltage.
The HF500-30 is available in a PDIP8-7B package.
