Abstract:
A switch-mode power supply includes a transformer, a power transistor, pulse generation circuitry, and a dual ramp modulation (DRM) circuit. The power transistor is coupled to a primary coil of the transformer. The pulse generation circuitry is configured to generate a power transistor activation signal. The DRM circuit is coupled to the pulse generation circuitry. The DRM circuit is configured to generate a leading edge blank time signal that disables inactivation of the power transistor activation signal for a predetermined interval (a leading edge blank time) after a leading edge of the power transistor activation signal. The DRM circuit is also configured to generate a reset signal that inactivates the power transistor activation signal while the leading edge blank time signal is activated.

Claim (Index 31):
A power supply controller, comprising:\n pulse generation circuitry configured to generate a pulse width modulation (PWM) signal including a rising edge and a falling edge, the pulse generation circuitry configured to delay the falling edge based on a leading edge blank time (LEB) signal, and configured to inhibit the LEB signal based on a reset signal; and a dual ramp modulation (DRM) circuit including:\n an LEB timer configured to disable the LEB signal based on a comparison between a ramp signal and a LEB reference voltage; and \n a reset circuit configured to generate the reset signal based on a comparison between the ramp signal and an adjusted LEB reference voltage offset by a feedback voltage derived from an output voltage of a switch-mode power supply.
