Description and Introduction

BiCMOS Low-Power Current Mode PWM Controller 8-SOIC 0 to 70 The UCC38C41DRG4 is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** UCC38C41DRG4  
- **Type:** Current-Mode PWM Controller  
- **Package:** SOIC-8  
- **Operating Temperature Range:** -40°C to +85°C  
- **Input Voltage Range (VCC):** 8.5V to 12V (start-up), 7.6V to 12V (operating)  
- **Output Drive Current:** ±1A (peak)  
- **Switching Frequency Range:** Up to 1MHz

- **Error Amplifier Gain Bandwidth:** 1MHz  
- **Propagation Delay:** 50ns  

### **Descriptions:**
The UCC38C41DRG4 is a high-speed, current-mode PWM controller designed for offline and DC-DC power supplies. It provides precise regulation and fast transient response, making it suitable for applications requiring high efficiency and reliability. The device includes features such as cycle-by-cycle current limiting, soft-start, and an internal oscillator for flexible frequency control.

### **Features:**
- **Current-Mode Control:** Enhances loop response and simplifies compensation.  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Programmable Soft-Start:** Reduces inrush current during startup.  
- **Cycle-by-Cycle Current Limiting:** Protects against overcurrent conditions.  
- **Internal Leading-Edge Blanking:** Improves noise immunity in current sensing.  
- **Low Start-Up Current:** Typically 0.5mA.  
- **Wide Operating Voltage Range:** Supports various power supply designs.  
- **Under-Voltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  

This information is strictly based on the manufacturer's datasheet and technical documentation.
