ABSTRACT:
A dual channel switching regulator is disclosed comprising a pair of current mode pulse width modulated controllers synchronized to a single oscillator with the input of the first one of pair of controllers being directly coupled to the oscillator while the input of the second one of the pair of controllers is coupled via an inverter to the output of the oscillator. The pair of controllers are thus operated on alternate half cycles of the output of the oscillator such that the turn off transients of one controller does not affect the other and vice versa. Hence, the switching regulator provides two independent regulated output voltages from an unregulated source.
