Description and Introduction

Automotive Catalog Improved Current Mode PWM Controller 16-SOIC -40 to 125 The UC2856QDWRQ1 is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Key Specifications:**  
- **Input Voltage Range:** 10V to 22V  
- **Operating Frequency:** Up to 1MHz  
- **Output Drive Current:** ±1.5A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 5MHz  
- **Soft-Start Control:** Adjustable  
- **UVLO (Undervoltage Lockout):** Adjustable  
- **Package:** SOIC-16 (D)  

### **Descriptions and Features:**  
- **Current-Mode Control:** Provides improved transient response and simplified loop compensation.  
- **Programmable Frequency:** Allows flexibility in design with external resistor and capacitor.  
- **High-Speed Error Amplifier:** Ensures fast response to load and line variations.  
- **Soft-Start Function:** Prevents excessive inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation only within the specified voltage range.  
- **Totem-Pole Outputs:** Capable of driving power MOSFETs directly.  
- **Thermal Shutdown Protection:** Protects the device from overheating.  

This device is commonly used in power supply applications such as AC/DC converters, DC/DC converters, and offline power supplies.
