Precision SWITCHMODE™
Pulse Width Modulator
Control Circuit
The MC34060A is a low cost fixed frequency, pulse width modulation
control circuit designed primarily for single–ended SWITCHMODE power
supply control.
The MC34060A is specified over the commercial operating temperature
range of 0° to +70°C, and the MC33060A is specified over an automotive
temperature range of –40° to +85°C.
