  • Publication number: 20240072667
    Abstract: A switching regulator includes a boost power stage circuit and a control circuit. The boost power stage circuit includes: at least one power switch configured to switch a terminal of an inductor according to an operation signal during a normal operation period, such that the terminal of the inductor is switched between an output voltage and ground level; and a power line switch connected in series to the inductor between the input voltage and the output voltage. The power line switch is turned OFF when the output voltage is short to ground level, to prevent a short current from flowing from input voltage to ground level. The control circuit generates the operation signal according to the output voltage and determines whether the power line switch is P-type or N-type MOS device, so as to turn OFF the power line switch when the output voltage is short to ground level.

  • Publication number: 20230121951
    Abstract: A remote control for a sickbed contains: a body, a calling assembly, an operational panel, and a switch. The body includes a power supply set, a microcontroller, a calling knob, and a wireless communication module. The operational panel includes multiple buttons so that when pressing any one of the multiple buttons, the microcontroller starts the transmission mechanism to actuate the sickbed to lift or descend. The switch is arranged on the body and moves close to or away from the calling knob. When the switch is pushed to abut against the calling knob, the calling knob is maintained on a locking position and does not generate a calling signal. When the switch is pushed to move away from the calling knob, the calling knob is maintained on a starting position and is pressed to conduct the power and to send the calling signal.
