Abstract:
1. An inverter controller with feed-forward compensation, comprising: an error amplifier for generating an amplified error voltage having a first input terminal for receiving a reference voltage, a second input terminal for receiving a feedback voltage, a third input terminal, and an output terminal; a comparator for providing a pulse width modulation (PWM) signal having a first input terminal, a second input terminal and an output terminal, the first input terminal of the comparator being coupled to the output terminal of the error amplifier; a driver for providing an output signal to an external circuit, the driver having an input terminal and an output terminal, the input terminal of the driver being coupled to the output terminal of the comparator and the output terminal of the driver providing the output signal to drive the external circuit; and an oscillator with feed-forward compensation having an output terminal coupled to the second input terminal of the comparator, the output terminal of the oscillator providing a signal with an amplitude proportional to a supply voltage.
