Description and Introduction

Current Mode PWM Controller 16-SOIC -40 to 85 The **UC2846DWTRG4** is a current-mode PWM controller manufactured by **Texas Instruments (TI)/Burr-Brown (BB)**. Below are its key specifications, descriptions, and features:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)/Burr-Brown (BB)  
- **Type:** Current-Mode PWM Controller  
- **Package:** SOIC-16 (DW)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Supply Voltage (VCC):** Up to 40V  
- **Output Current (Source/Sink):** 200mA (Peak)  
- **Switching Frequency:** Adjustable up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 1MHz  
- **Reference Voltage:** 5V (±1%)  

### **Descriptions:**  
The UC2846DWTRG4 is a high-performance PWM controller designed for switching power supply applications. It operates in **current-mode control**, providing improved loop response and simplified compensation. The device includes an **onboard oscillator, error amplifier, current-sensing comparator, and totem-pole outputs** for driving power MOSFETs or IGBTs.  

### **Features:**  
- **Current-Mode Control** for enhanced transient response  
- **Programmable Oscillator** with sync capability  
- **Precision 5V Reference** (±1% tolerance)  
- **Soft-Start Control** for controlled startup  
- **Undervoltage Lockout (UVLO)** for protection  
- **Dual Alternating Outputs** for push-pull or half-bridge configurations  
- **High-Current Totem-Pole Outputs** (200mA peak)  
- **Adjustable Dead-Time Control**  
- **Low Startup Current** (<1mA)  

This device is commonly used in **DC-DC converters, offline power supplies, and motor control applications**.
