  • Boost spread-spectrum technique in pulse skip mode with fixed frequency clock reference
    Patent number: 11005367
    Abstract: A boost DC-DC switching converter architecture is provided, with a spread spectrum technique working in pulse skip mode, and a fixed frequency clock reference, comprising a high side switch and a low side switch, controlled by a voltage or current mode control loop operating in a Pulse Width Modulation (PWM) mode, and having a pulse skip mode. The switching converter comprises an inductor, connected between an input voltage terminal and the high side switch, and also connected to the low-side switch, and a random delay generator, where the random delay generator randomly varies a time for entering, or exiting, or both entering and exiting pulse skip mode, and varies a time where the high side switch is turned off in pulse skip mode.
