MPS HFC0300 Variable Off Time ControllerMonolithic Power Systems HFC0300 Variable Off Time Controller uses a fixed-peak-current technique to decrease its frequency as the load lightens. As a result, the HFC0300 Variable Off Time Controller
offers excellent efficiency at light-load while optimizing the
efficiency under other load conditions. When the frequency decreases to
threshold, the peak current decreases to
prevent mechanical resonance in the transformer. MPS' HFC0300 Variable Off Time Controller enters burst mode when the output power falls below a given level. Features for the Monolithic Power Systems HFC0300 Variable Off Time Controller includes various protections such as thermal shutdown, VCC under-voltage lockout, overload protection, short-circuit protection, and over-voltage protection.
