摘要: A current mode switching regulator implementing a dual sense scheme includes first sensing circuit for through switch and providing signal, second signal. The control generating signals driving the switches in response to one of signals. further duty cycle detection coupled determine regulator. asserts select signal when exceeds threshold level is less than level.
