Description and Introduction

Current Mode PWM Controller 8-PDIP -40 to 85 The UC2844ANG4 is a high-performance current-mode PWM controller manufactured by Texas Instruments.  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage Range:** Up to 30V (operating)  
- **Output Drive Current:** ±1A (peak)  
- **Switching Frequency:** Up to 500kHz  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 1MHz  
- **Start-Up Current:** <1mA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  

### **Descriptions & Features:**  
- **Current-Mode Control:** Provides cycle-by-cycle current limiting for improved transient response.  
- **Under-Voltage Lockout (UVLO):** Ensures proper start-up and shutdown behavior.  
- **Programmable Oscillator:** Allows external timing components for frequency adjustment.  
- **Soft-Start Capability:** Reduces inrush current during start-up.  
- **High-Current Totem Pole Output:** Directly drives power MOSFETs.  
- **Internal Trimmed Bandgap Reference:** Provides stable 5V reference (±1% accuracy).  
- **Pulse-by-Pulse Current Limiting:** Enhances system reliability.  
- **Low-Power Standby Mode:** Reduces power consumption when inactive.  

This IC is commonly used in switch-mode power supplies (SMPS), DC-DC converters, and offline power applications.
