Description and Introduction

HIGH PERFORMANCE DUAL CHANNEL CURRENT MODE CONTROLLERS The MC33065P-H is a high-voltage power factor controller manufactured by Motorola (MOTO). Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**
- **Manufacturer:** Motorola (MOTO)  
- **Type:** Power Factor Controller (PFC)  
- **Package:** PDIP-16 (Plastic Dual In-line Package)  
- **Operating Voltage Range:** Up to 600V  
- **Operating Temperature Range:** -40°C to +105°C  
- **Frequency Range:** Adjustable, typically up to 250kHz  
- **Current Sense Input:** Yes  
- **Multiplier Input:** Yes  
- **ZCD (Zero-Crossing Detector):** Included  
- **Error Amplifier:** Built-in  

### **Descriptions:**
The MC33065P-H is designed for high-efficiency power factor correction in AC-DC power supplies. It incorporates critical control functions to improve power factor and reduce harmonic distortion in switch-mode power supplies. It is commonly used in applications requiring compliance with power quality standards.

### **Features:**
- **High-Voltage Operation:** Supports up to 600V for robust power handling.  
- **Power Factor Correction (PFC):** Ensures efficient power usage by aligning current and voltage phases.  
- **Precision Multiplier:** Enhances control accuracy for PFC applications.  
- **Zero-Crossing Detection (ZCD):** Improves efficiency by detecting voltage zero crossings.  
- **Programmable Oscillator:** Allows adjustable switching frequency.  
- **Overvoltage Protection (OVP):** Safeguards against excessive voltage conditions.  
- **Error Amplifier:** Provides feedback control for stable operation.  
- **Current Sensing:** Enables precise current monitoring for protection and regulation.  

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

Application Scenarios & Design Considerations

HIGH PERFORMANCE DUAL CHANNEL CURRENT MODE CONTROLLERS

Alternative Part Number

  • SG3525AN --: Industry-standard dual PWM controller with same function and DIP-16 pinout, widely available and often used as a direct substitute for MC33065-type regulators.
  • TL494CN --: Very common dual-output PWM control IC with similar voltage-mode control features and DIP-16 package, suitable for many designs using the MC33065.
  • UC3525AN --: Equivalent-class regulating PWM controller from the UC3525 series, offering comparable oscillator and output driver characteristics in a DIP-16 package.
