Description and Introduction

V(cc): 65V; 70mA; ; power switching regulator The MC33165DW is a high-performance, fixed-frequency current-mode PWM controller manufactured by ON Semiconductor.  

### **Key Specifications:**  
- **Input Voltage Range:** 8V to 40V  
- **Output Frequency:** 100 kHz (fixed)  
- **Output Current (Source/Sink):** 1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** SOIC-16  

### **Descriptions and Features:**  
- **Current-Mode Control:** Provides improved transient response and simplified loop compensation.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation by disabling the output when the supply voltage is too low.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Error Amplifier:** Features a high-gain bandwidth for precise regulation.  
- **Pulse-by-Pulse Current Limiting:** Enhances system protection.  
- **Totem Pole Output:** Optimized for driving power MOSFETs.  
- **Low Startup Current:** Typically 0.5 mA for efficient operation.  

This IC is commonly used in switch-mode power supplies (SMPS), DC-DC converters, and other power management applications.
