Description and Introduction

Precision Switchmode Pulse Width Modulator Control Circuit The MC34060ADR2 is a monolithic oscillator and timer circuit manufactured by Motorola (now part of ON Semiconductor). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
- **MOT** (Motorola, now part of ON Semiconductor)  

### **Specifications:**  
- **Type:** Precision Timer/Oscillator  
- **Package:** SOIC-16  
- **Operating Voltage Range:** 3V to 32V  
- **Timing Capacitance Range:** 100pF to 100µF  
- **Timing Resistance Range:** 1kΩ to 20MΩ  
- **Frequency Stability:** ±2% (over temperature)  
- **Output Current:** Up to 200mA (sink or source)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
- The MC34060ADR2 is a highly stable controller capable of producing accurate time delays or oscillations.  
- It combines a linear ramp generator, comparator, and output driver in a single package.  
- Suitable for applications requiring precision timing, pulse generation, or sequential timing.  

### **Features:**  
- **Adjustable Duty Cycle:** Allows for precise control of output pulse width.  
- **Temperature-Compensated Reference:** Ensures stable operation across temperature variations.  
- **High Output Drive Capability:** Can directly drive TTL, CMOS, or relays.  
- **Low Power Consumption:** Optimized for battery-operated applications.  
- **Wide Operating Voltage Range:** Supports 3V to 32V operation.  
- **Monolithic Design:** Provides high reliability and integration.  

This information is based solely on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Precision Switchmode Pulse Width Modulator Control Circuit

Alternative Part Number

  • SG3524DR --: Industry-standard PWM controller with the same function and pinout family as the MC34060A, widely available and well documented.
  • TL494CDR --: Very common fixed-frequency PWM control IC covering the same application space, easy drop-in for many MC34060A designs with minor component tuning.
  • UC3842BD1R2G --: Current-mode PWM controller from a different series that can replace the MC34060A in many switching supply designs, with good availability and similar SOIC package.
  • UC3842AN --: Current-mode PWM controller often used where MC34060A was applied; requires minor circuit adjustment but is a well-supported alternative for offline converter designs.
