Description and Introduction

High Speed PWM Controller The UC1825J is a high-speed PWM controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Package:** 16-CDIP (Ceramic Dual In-Line Package)  
- **Operating Temperature Range:** -55°C to +125°C  
- **Supply Voltage (VCC):** Up to 40V  
- **Output Current (Source/Sink):** 2A Peak  
- **Switching Frequency:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 10MHz  
- **Propagation Delay:** 50ns  

### **Description:**  
The UC1825J is a high-performance pulse-width modulation (PWM) controller designed for power supply applications. It features fast response times, high-frequency operation, and precise duty cycle control. The device is suitable for switching regulators, DC-DC converters, and motor control applications.  

### **Features:**  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Precision Reference:** 5.1V ±1% trimmed bandgap reference.  
- **Programmable Dead Time:** Adjustable dead-time control for shoot-through prevention.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Dual Alternating Outputs:** Push-pull configuration for half-bridge or full-bridge topologies.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Current-Limiting Protection:** Prevents damage from excessive load conditions.  
- **Error Amplifier:** High-gain, wide-bandwidth amplifier for feedback loop control.
