Claim 0:
1. A boost converter control system comprising:
a gate driver coupled to a switch of a boost converter to generate a drive signal to control switching of the switch, the drive signal having a period and an ON time, wherein a period of the drive signal is adjusted using a current adjustment signal;
a current control loop coupled to the gate driver to receive a sensed input current from the boost converter and a desired input current and to generate the current adjustment signal to the gate driver; and
a current limiter coupled to the gate driver and the current control loop to determine a duty cycle of the switch, to determine a maximum input current in response to the duty cycle, and to restrict the desired input current to below the maximum input current.
