Description and Introduction

High Speed Double-Ended PWM Controller The MC33025DW is a high-performance PWM controller manufactured by Motorola. Below are its specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** Motorola (now part of ON Semiconductor)  
- **Package:** SOIC-16 (DW suffix indicates wide-body SOIC package)  
- **Operating Voltage Range:** 8V to 18V (with 36V absolute maximum)  
- **Output Current (Peak):** 1A (sink/source)  
- **Switching Frequency:** Up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 5MHz  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MC33025DW is a pulse-width modulation (PWM) controller designed for high-efficiency power supply and motor control applications. It features a push-pull output stage, making it suitable for driving power MOSFETs or IGBTs in half-bridge or full-bridge configurations.  

### **Features:**  
- **Push-Pull Outputs:** Two totem-pole outputs for driving external power switches.  
- **Programmable Deadtime Control:** Adjustable deadtime to prevent shoot-through in bridge circuits.  
- **Error Amplifier:** High-gain, wide-bandwidth operational amplifier for feedback control.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within voltage limits.  
- **Current-Limiting Protection:** Includes cycle-by-cycle current limiting.  
- **Synchronization Capability:** Allows external clock synchronization for multi-phase operation.  

This information is derived from the manufacturer's datasheet and technical documentation.
