The above figure shows the MC34161 configured as a step–down converter. Channel 1 monitors the output voltage while Channel 2
performs the oscillator function. Upon initial power–up, the converters output voltage will be below nominal, and the output of Channel
1 will allow the oscillator to run. The external switch transistor will eventually pump–up the output capacitor until its voltage exceeds the
input threshold of Channel 1. The output of Channel 1 will then switch low and disable the oscillator. The oscillator will commence
operation when the output voltage falls below the lower threshold of Channel 1.
