Description and Introduction

BiCMOS Low-Power Current Mode PWM Controller The UCC28C40P is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:  

### **Specifications:**  
- **Manufacturer:** Texas Instruments (TI)  
- **Type:** Current-Mode PWM Controller  
- **Topology:** Flyback, Forward, Boost, Buck  
- **Operating Frequency:** Up to 1 MHz  
- **Supply Voltage (VCC):** 8.4V to 18V (start-up), 7.6V (UVLO turn-off)  
- **Output Current (Source/Sink):** 1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 5 MHz  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 8-Pin PDIP  

### **Descriptions:**  
The UCC28C40P is a versatile PWM controller designed for high-frequency DC-DC power conversion applications. It operates in current-mode control, providing improved loop response and simplified compensation. The device includes features like programmable oscillator frequency, cycle-by-cycle current limiting, and undervoltage lockout (UVLO) for robust operation.  

### **Features:**  
- **Current-Mode Control:** Enhances transient response and simplifies loop compensation.  
- **Programmable Oscillator:** Adjustable frequency up to 1 MHz using external components.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within the supply voltage range.  
- **Cycle-by-Cycle Current Limiting:** Protects against overloads.  
- **High-Current Totem Pole Output:** 1A peak drive for fast switching of power MOSFETs.  
- **Wide Operating Temperature Range:** Suitable for industrial and automotive applications.  

This information is based on TI's official datasheet and product documentation.
