Description and Introduction

HIGH PERFORMANCE CURRENT MODE PWM CONTROLLER The UC2845AN is a high-performance current-mode PWM controller manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 8V to 30V (operating), up to 36V (absolute max)  
- **Output Current:** ±1A (peak)  
- **Switching Frequency:** Up to 500kHz  
- **Duty Cycle Range:** 0% to 100% (adjustable)  
- **Reference Voltage:** 5V (±1% accuracy)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-pin PDIP (Plastic Dual In-line Package)  

### **Descriptions:**  
- The UC2845AN is a fixed-frequency pulse-width modulation (PWM) controller designed for DC-DC converter and power supply applications.  
- It operates in current-mode control, providing improved loop response and simplified feedback compensation.  
- Includes features like under-voltage lockout (UVLO), cycle-by-cycle current limiting, and a totem-pole output stage for driving power MOSFETs.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies feedback loop design.  
- **Under-Voltage Lockout (UVLO):** Ensures proper startup and shutdown behavior.  
- **Programmable Oscillator:** Allows external adjustment of switching frequency.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Error Amplifier:** Provides high-gain bandwidth for precise regulation.  
- **Latch-Free Operation:** Ensures fault recovery without external reset.  
- **Totem-Pole Output:** Directly drives power MOSFETs with high peak current capability.  

The UC2845AN is widely used in offline and DC-DC converters, battery chargers, and power supply systems.
