Description and Introduction

BiCMOS Low-Power Current Mode PWM Controller The UCC38C44 is a high-performance current-mode PWM controller manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 10V to 30V  
- **Operating Frequency Range:** Up to 1MHz  
- **Output Drive Current:** ±1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Error Amplifier Bandwidth:** 5MHz  
- **Soft-Start Capability:** Yes  
- **Undervoltage Lockout (UVLO):** 8.4V (on) / 7.6V (off)  
- **Current Sense Comparator Delay:** 100ns  
- **Package Options:** SOIC-8, PDIP-8  

### **Descriptions:**  
The UCC38C44 is designed for high-frequency switching power supplies, providing precise control in current-mode topologies. It features a fast error amplifier, cycle-by-cycle current limiting, and a programmable oscillator.  

### **Features:**  
- **Current-Mode Control:** Improves transient response and simplifies loop compensation.  
- **Programmable Frequency:** Adjustable via external resistor and capacitor.  
- **Soft-Start:** Reduces inrush current during startup.  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Low Startup Current:** Typically 0.5mA.  
- **Error Amplifier with High Bandwidth:** Ensures fast response to load changes.  
- **UVLO Protection:** Ensures reliable operation under low-voltage conditions.
