| titleOfInvention | Quasi-resonance control circuit and its Valley-Switching method |
| abstract | Disclose a kind of control circuit and Valley-Switching method controlled for quasi-resonance in switch converters.The control circuit includes that switch mode setting unit and valley signal generation unit are used for the lowest point signal detection.Mode setting unit is switched to be used for the control terminal floating of main switch after main switch turns off a period of time.After control terminal floating, when the decline of main switch end voltage, by the voltage clamping in main switch control terminal in the first reference voltage；When main switch end voltage rises, clamper failure, control terminal voltage rises；When control terminal voltage rises to the second reference voltage, represents main switch end voltage and reach valley, main switch conducting.The control circuit does not need the optimal value of the variation adjustment detection main switch end voltage dips with parameter, while in specific IC design, it is only necessary to which multiplexing driving pin can carry out valley detection without additional voltage acquisition pin. |
