POWER CONVERTER CONTROL WITH SNOOZE MODE

Abstract:

A control signal generator includes an error amplifier, a first comparator, a second comparator, a logic circuit and a pulse generator. The error amplifier has a first output, a first input, a second input and a first snooze input. The first comparator has a second output, a third input and a fourth input. The third input is coupled to the first output. The second comparator has a third output, a fifth input, a sixth input and a second snooze input. The fifth input is coupled to the third input. The logic circuit has a fourth output and logic circuit inputs, including a first logic circuit input coupled to the second output. The pulse generator has a fifth output and a seventh input. The seventh input is coupled to the fourth output. A snooze mode controller has a sixth output coupled to the first snooze input and the second snooze input.
