摘要： The present invention discloses a voltage conversion apparatus and a power-ON reset (POR) circuit and a control method thereof. The voltage conversion apparatus includes: a conversion circuit, an input status detection circuit, an output status detection circuit, a status feedback circuit, and a POR circuit. The POR circuit generates a POR signal according to an input status signal, an output status signal, and a feedback signal, to indicate whether a POR procedure is completed. The POR circuit includes: a logic circuit, for generating a reset signal indicating whether both the input and output voltages are ready; and a delay circuit, for generating the POR signal by delaying a predetermined time period according to the reset signal and a feedback signal related to the POR signal.

摘要： A driver circuit for a Light Emitting Diode (LED) is disclosed. The driver circuit is capable of supporting a constant LED current circuit configuration as well as an external resistor-controlled LED current circuit configuration. By integrating both configurations into a single driver circuit, the either circuit configuration can be selected without requiring a different driver circuit.
