EVHF300-J-00A

The EVHF300-J-00A is an evaluation board designed to demonstrate the capabilities of the HF300, an ideal clamping controller. The HF300 is an intelligent, high-frequency flyback ideal clamping controller that can be used to replace the passive resistor-capacitor-diode (RCD) snubber in a flyback circuit to clamp the drain-to-source voltage spike that is caused by the leakage inductance (L_LKG) after the primary main switch (e.g. MOSFET) turns off.

The HF300 is compatible with many flyback modes, such as continuous conduction mode (CCM), discontinuous conduction mode (DCM), quasi-resonant (QR) operation, and zero-voltage switching (ZVS) operation. It can also support up to 300kHz flyback applications, and can simultaneously improve flyback circuit efficiency.

The HF300 is an ideal substitute for a traditional RCD passive snubber, without significantly increasing the complexity or cost of the system. The HF300 offers full protection features and flexible parameter settings, which ensures safe operation of the flyback circuit.

The HF300 is available in a space-saving TSOT23-6 package.
