Patent ID: 8643349

Claim:
A power supply controller, comprising: a pulse width modulation control module having an input and an output; and a feedback network having a first input and an output, the output connected to the input of the pulse width modulation control module, wherein the feedback network includes: an amplifier having an inverting input terminal, a non-inverting input terminal, and an output terminal; a compensation network having first and second nodes; and a switch having first and second current conducting terminals and a control terminal, the first current conducting terminal coupled to the first node of the compensation network and the second current conducting terminal coupled to the output terminal of the amplifier and to the input of the pulse width modulation control module, and the control terminal coupled to the output of the pulse width modulation control module, wherein the feedback network operates in an open loop configuration in response to the switch being open and in a closed loop configuration in response to the switch being closed.
