Description and Introduction

Current Mode PWM Controller The UC1846JQMLV is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** UC1846JQMLV  
- **Type:** Current-Mode PWM Controller  
- **Operating Temperature Range:** -55°C to +125°C (Military Grade)  
- **Supply Voltage (VCC):** Up to 40V  
- **Output Current:** 500mA (Peak)  
- **Switching Frequency:** Up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Package:** 16-Pin CDIP (Ceramic Dual In-Line Package)  
- **Qualification Level:** QML (Qualified Manufacturers List) for high-reliability applications  

### **Descriptions and Features:**  
- **Current-Mode Control:** Provides cycle-by-cycle current limiting for improved transient response.  
- **Programmable Oscillator:** Allows adjustable switching frequency via external components.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Error Amplifier:** Includes a high-gain bandwidth error amplifier for precise regulation.  
- **Synchronization Capability:** Can be synchronized to an external clock.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation by disabling outputs when VCC is too low.  
- **Dual Output Drivers:** Push-pull outputs for driving power MOSFETs or bipolar transistors.  
- **High Reliability:** Designed for military and aerospace applications with extended temperature range.  

This device is commonly used in power supply designs requiring precise control and high reliability.
