Description and Introduction

BiCMOS Low Current 8 Pin PWM Current Mode Controller The UCC28C42D is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI) under the UNITRODE brand.  

### **Specifications:**  
- **Topology:** Current-mode PWM controller  
- **Input Voltage Range (VCC):** 8.5V to 18V (operating), 7.5V (UVLO turn-on), 6.5V (UVLO turn-off)  
- **Output Drive Current:** ±1A (peak)  
- **Switching Frequency Range:** Up to 1MHz  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 5MHz  
- **Propagation Delay:** 50ns  
- **Operating Temperature Range:** -40°C to +105°C  
- **Package:** SOIC-8 (D)  

### **Descriptions and Features:**  
- **Current-Mode Control:** Provides cycle-by-cycle current limiting for improved transient response.  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Under-Voltage Lockout (UVLO):** Ensures proper start-up and shutdown.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Error Amplifier:** High-gain bandwidth (5MHz) for precise regulation.  
- **Low Power Consumption:** Optimized for efficiency.  
- **Wide Temperature Range:** Suitable for industrial applications.  
- **Protection Features:** Includes pulse-by-pulse current limiting and latch-off for overcurrent protection.  

This PWM controller is commonly used in power supply designs, including DC-DC converters, offline power supplies, and battery chargers.
