  • Patent number: 10651750
    Abstract: A constant on-time isolated converter comprises a transformer with a primary side and a secondary side. The primary side is connected to an electronic switch and secondary-side is connected to a load and a processor. The processor is connected to a driver on primary side through at least one coupling element and to the electronic switch. The processor receives an output voltage or an output current across the load generating a control signal accordingly. The driver receives the control signal through the coupling element and accordingly changes the ON/OFF state of the electronic switch, regulating the output voltage and the output current via the transformer, where the duration of the ON/OFF state of the electronic switch is determined between the moment control signal changes from negative to positive and the moment it changes from positive to negative to achieve a high-speed load transient response.

  • Publication number: 20190318464
    Abstract: A fingerprint identification module test system includes a light source, a projection surface, a low-end image pickup device and a judgment module. The light source emits and projects a light beam onto an under-test fingerprint identification module. After the light beam is reflected by the under-test fingerprint identification module and projected onto the projection surface, a projected image is formed on the projection surface. Then, the low-end image pickup device photographs the projected image to acquire an under-test corresponding to the under-test fingerprint identification module. According to the result of comparing the under-test image with the predetermined image, the judgment module judges whether the under-test fingerprint identification module complies with the production specifications. Since the fingerprint identification module test system uses parity devices to test the under-test fingerprint identification module, the fingerprint identification module test system is cost-effective.
