Abstract
A half-bridge driver circuit periodically repeats switching cycles by closing a first FET via a first drive signal, detecting an instant when a current flowing through the first FET reaches a threshold and then opening the first FET and closing a second FET via a second drive signal. An error amplifier generates a control voltage by comparing a feedback signal with a reference signal, and a variable current generator generates a first current as a function of the control voltage. The error amplifier includes a proportional-integral controller, and a slope compensation circuit that generates a second current as a ramp signal. The threshold is generated by subtracting the second current from the first current. In response to detecting the instant, the second current is sampled and a signal indicative of the threshold is generated by subtracting the sampled second current from the first current.
