Patent ID: 7414385

Claim:
A chipset comprising: a first primary controller comprising: control and drive circuitry; a high speed oscillator having integrated feed forward compensation providing immediate duty cycle adjustment while maintaining a constant oscillator frequency; a soft start circuit; a band gap circuit coupled to the soft start circuit to produce an accurate reference; a pulse width modulation circuit coupled to the soft start circuit; an output circuit coupled to the pulse width modulation circuit, wherein the output circuit feeds the output of the first primary controller; a secondary controller to provide rectification signals coupled to the first primary controller, the secondary controller comprising: a band gap circuit for producing an accurate reference coupled to a Schmitt trigger, a comparator, a bias net circuit and an over-voltage lockout circuit; and at least two latches coupled to at least two detectors, wherein the latches are coupled to the Schmitt trigger; a first gate driver connected to the first primary controller; and a second gate driver connected to the secondary controller.
