Description and Introduction

High Speed Single-Ended PWM Controller The MC33023DW is a high-performance PWM controller manufactured by ON Semiconductor.  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 40V  
- **Operating Frequency:** Up to 100kHz  
- **Output Current (Source/Sink):** 200mA (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 1MHz  
- **Soft-Start Capability:** Yes  
- **Undervoltage Lockout (UVLO):** Adjustable  
- **Package:** SOIC-16 (DW suffix)  

### **Descriptions:**  
The MC33023DW is a fixed-frequency pulse-width modulation (PWM) controller designed for DC-DC converter applications. It features a precision reference, error amplifier, oscillator, PWM comparator, and high-current totem-pole output drivers. It is suitable for push-pull, half-bridge, and full-bridge topologies.  

### **Features:**  
- **High-Speed Operation:** Optimized for switching power supplies.  
- **Programmable Deadtime Control:** Prevents shoot-through in bridge circuits.  
- **Current-Limiting Protection:** Enhances system reliability.  
- **Sync Capability:** Allows synchronization with an external clock.  
- **Temperature Stability:** Designed for industrial temperature ranges.  
- **Soft-Start Function:** Reduces inrush current during startup.  

This IC is commonly used in power supply designs, motor control, and industrial applications.
