  • Non-linear compensation ramp for current mode pulse width modulation
    Patent number: 8138740
    Abstract: A current mode direct current-to-direct current (DC-to-DC) voltage regulator controls its output voltage using a pulse width modulation (PWM) circuit that employs a non-linear compensation ramp. By employing such a PWM circuit, the output voltage can be controlled more robustly over a wider range of operating conditions.
