Description and Introduction

Current Mode PWMs The UC3845AM is a current-mode PWM controller manufactured by LINFIMITY. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Input Voltage Range:** 8V to 30V  
- **Output Frequency:** Up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Output Current:** ±200mA (peak)  
- **Reference Voltage:** 5V (±1%)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package Type:** SOIC-8  

### **Descriptions:**  
The UC3845AM is a fixed-frequency PWM controller designed for DC-DC converter applications. It operates in current-mode control, providing precise regulation and improved loop response. It includes features like under-voltage lockout (UVLO), cycle-by-cycle current limiting, and a totem-pole output for driving power MOSFETs.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation within the specified voltage range.  
- **Adjustable Oscillator Frequency:** Allows flexibility in design.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Error Amplifier:** Provides high gain-bandwidth for accurate feedback control.  
- **Totem-Pole Output:** Directly drives power MOSFETs.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  

This information is based on the manufacturer's datasheet for the UC3845AM.
