Description and Introduction

Switched Mode Controller for DC Motor Drive The UC1637J/883B is a high-performance PWM (Pulse-Width Modulation) controller manufactured by Texas Instruments. Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Manufacturer:**  
Texas Instruments  

### **Part Number:**  
UC1637J/883B  

### **Description:**  
The UC1637J/883B is a high-speed PWM controller designed for precision power supply and motor control applications. It is part of the UC1637 series and is qualified for military and aerospace applications (indicated by the **/883B** suffix).  

### **Key Features:**  
- **High-Speed Operation:** Capable of high-frequency switching for efficient power conversion.  
- **Wide Supply Voltage Range:** Operates from **4.5V to 40V**.  
- **Adjustable Deadtime Control:** Allows precise control of switching delays.  
- **Dual Output Drivers:** Provides push-pull outputs for driving power MOSFETs or IGBTs.  
- **Error Amplifier:** Includes an onboard error amplifier for feedback loop control.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation by disabling outputs if supply voltage is too low.  
- **Temperature Range:** Designed for **-55°C to +125°C** operation (military-grade).  
- **Radiation Hardened:** Meets MIL-PRF-38535 standards for high-reliability applications.  

### **Applications:**  
- Switch-mode power supplies (SMPS)  
- DC-DC converters  
- Motor control systems  
- Aerospace and military power systems  

### **Package:**  
Ceramic DIP (Dual In-line Package) for high-reliability applications.  

This information is strictly based on the manufacturer's datasheet and specifications. No additional guidance or suggestions are included.
