Product Detail

HFC0300 is a variable off-time controller that uses a fixed-peak?urrent technique to decrease its frequency as the load lightens. As a result, it offers excellent efficiency at light-load while optimizing the efficiency under other load conditions. When the frequency decreases to threshold, the peak current decreases with the decreasing load to prevent mechanical resonance in the transformer. The controller enters burst mode when the output power falls below a given level.?The HFC0300 features various protections such as thermal shutdown, VCC under-voltage lockout, overload protection, short-circuit protection, and over-voltage protection.?The HFC0300 is available in SOIC-7 package.
