Description and Introduction

Linear High-Performance Current Mode Controller The UC2843AD1 is a high-performance current-mode PWM controller manufactured by STMicroelectronics (ST).  

### **Key Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage (VCC):** 8.4V to 30V (operating range)  
- **Under-Voltage Lockout (UVLO):** 8.4V (turn-on), 7.6V (turn-off)  
- **Output Current (Peak):** ±1A (source/sink)  
- **Switching Frequency:** Up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 1MHz  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions & Features:**  
- Designed for offline and DC-DC converter applications.  
- Features a trimmed oscillator for precise duty cycle control.  
- Includes a high-gain error amplifier for tight voltage regulation.  
- Current-sensing comparator for cycle-by-cycle current limiting.  
- Built-in soft-start functionality for controlled startup.  
- Latchable PWM for single-pulse metering.  
- Low startup and operating current.  
- Protection features include under-voltage lockout (UVLO) and current limiting.  

This IC is commonly used in power supply designs, including flyback, forward, and boost converters.
