Abstract
A switching power converter for DC-DC converting has an inductance coupled between a power output and a high side switch in a controller device. The controller device has an error amplifier coupled to the power output and a reference voltage for activating the high side switch. The controller device has a bypass circuit including a bypass switch coupled between the supply input and the power output, a bypass driver having a first input coupled to the power output and a second input coupled to the reference voltage, and an output coupled to the bypass switch for activating the bypass switch. The controller further has a high bypass current sensor for generating a transient signal based on a current via the bypass switch, and a bandwidth control circuit for increasing the bandwidth of the error amplifier based on the transient signal.
