MC34060A, MC33060A
Fixed Frequency, PWM,
Voltage Mode Single Ended
Controllers
The MC34060A is a low cost fixed frequency, pulse width
modulation control circuit designed primarily for single−ended
SWITCHMODEt 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.
Features
• Complete Pulse Width Modulation Control Circuitry
• On−Chip Oscillator with Master or Slave Operation
• On−Chip Error Amplifiers
• On−Chip 5.0 V Reference, 1.5% Accuracy
• Adjustable Dead−Time Control
• Uncommitted Output Transistor Rated to 200 mA Source or Sink
• Undervoltage Lockout
• These are Pb−Free and Halide−Free Devices
