Description and Introduction

CURRENT MODE PWM CONTROLLER The SG3845N is a pulse width modulation (PWM) controller IC manufactured by ON Semiconductor. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 8V to 30V  
- **Operating Frequency Range:** Up to 500 kHz  
- **Output Duty Cycle Range:** 0% to 100%  
- **Output Current (Source/Sink):** 200 mA (peak)  
- **Reference Voltage:** 5.1V (±1%)  
- **Error Amplifier Gain Bandwidth:** 1 MHz  
- **Soft-Start Capability:** Adjustable  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** PDIP-16  

### **Descriptions:**  
The SG3845N is a fixed-frequency current-mode PWM controller designed for DC-DC converter and power supply applications. It provides precise control over switching power supplies with features like adjustable duty cycle, soft-start, and under-voltage lockout (UVLO).  

### **Features:**  
- **Current-Mode Operation** for improved transient response  
- **Latching PWM** for cycle-by-cycle current limiting  
- **Under-Voltage Lockout (UVLO)** with hysteresis  
- **Programmable Soft-Start**  
- **Synchronizable Oscillator**  
- **Double-Pulse Suppression**  
- **High-Current Totem Pole Output**  
- **Low Startup Current (<1 mA)**  

This information is based solely on manufacturer datasheets and technical documentation.
