Application: Switching power supply device (Patent ID: US20240213879A1)
The patent filed by Denso Corp describes a switching power supply device that includes an on-timing generation circuit utilizing an error amplifier, common voltage generation unit, ripple signal generation unit, and comparator to generate an on-timing signal for turning on a switching element. The device converts input voltage to output voltage through pulse width modulation control, with fixed on-state time, and includes circuits for generating drive signals and driving the switching element based on these signals.
The claims of the patent detail the components and functions of the switching power supply device, including the generation of forward and reverse phase ripple signals based on the input voltage, utilization of capacitors for charging and discharging proportional to input voltage, and comparison circuits for generating on-timing signals and on-state time signals. The patent also specifies the use of common components across different circuits within the device, such as the forward phase capacitor being utilized in both the ripple signal generation unit and the on-state time generation circuit.
