Description and Introduction

Current Mode PWM Controller The UC3846DWTR is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Output Type:** Dual, Totem Pole  
- **Topology:** Boost, Flyback, Forward  
- **Switching Frequency:** Up to 500 kHz  
- **Duty Cycle (Max):** 50%  
- **Supply Voltage (Vcc):** 8V to 40V  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-16 (DW)  
- **Output Current (Source/Sink):** 200mA / 400mA  
- **Error Amplifier Bandwidth:** 5 MHz  
- **Under-Voltage Lockout (UVLO):** 8V (on), 7.6V (off)  

### **Descriptions:**  
The UC3846DWTR is a fixed-frequency pulse-width modulation (PWM) controller designed for high-performance power supply applications. It features current-mode control, which improves loop response and simplifies compensation. The device includes a precision reference, error amplifier, oscillator, and high-current totem-pole outputs for driving power MOSFETs or IGBTs.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies feedback loop compensation.  
- **Programmable Oscillator:** Allows flexible frequency adjustment using external components.  
- **Synchronization Capability:** Can be synchronized to an external clock.  
- **Soft-Start Function:** Reduces inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Protects against overloads.  
- **Error Amplifier with High Bandwidth:** Ensures fast response to load changes.  
- **Wide Operating Voltage Range:** Supports 8V to 40V input.  
- **High-Current Output Drivers:** Capable of driving power MOSFETs directly.  

This device is commonly used in switch-mode power supplies (SMPS), DC-DC converters, and motor control applications.
