Abstract
A current mode DC/DC converter provided with a current mode control circuit serving as a feedback circuit for stabilizing an output voltage Vo supplied to a load resister RL, which detects a coil current I flowing through a choke coil L and control switching operation of a switching element Q according to a result of comparison between a detection signal of the coil current I and an error signal from an error amplifier A serving as a reference signal. The current mode control circuit is provided with a feed forward circuit which detects a variation in a load current Io flowing through a load resister RL and adds the variation to the detection signal of a coil current I Accordingly, a switching pulse, by which the coil current I changes quickly in response to an abrupt change in the load current Io, can be fed to the switching element Q
