Conditions
V in = 9.5 V to 24 V, I O = 250 mA
V in = 12 V, I O = 0.25 mA to 250 mA
V in = 12 V, I O = 250 mA
V in = 12 V, I O = 250 mA
Results
40 mV = ± 0.1%
2.0 mV = ± 0.2%

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 powerup, 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.
