Description and Introduction

Low-Power BiCMOS Current-Mode PWM The UCC3800D is a high-speed, low-power BiCMOS PWM controller manufactured by UNITRODE. Below are the specifications, descriptions, and features based on factual information:

### **Specifications:**  
- **Manufacturer:** UNITRODE  
- **Type:** BiCMOS PWM Controller  
- **Operating Voltage Range:** 4.5V to 12V  
- **Operating Frequency:** Up to 1MHz  
- **Quiescent Current:** 1.5mA (typical)  
- **Output Drive Current:** ±1A (peak)  
- **Duty Cycle Range:** 0% to 100%  
- **Propagation Delay:** 50ns (typical)  
- **Temperature Range:** -40°C to +85°C  
- **Package:** SOIC-8  

### **Descriptions:**  
The UCC3800D is a high-performance pulse-width modulation (PWM) controller designed for power supply applications. It is optimized for low-power, high-frequency DC-DC converters. The device features a fast response time, making it suitable for voltage-mode and current-mode control schemes.  

### **Features:**  
- **High-Speed Operation:** Supports switching frequencies up to 1MHz.  
- **Low Power Consumption:** Quiescent current as low as 1.5mA.  
- **Wide Input Voltage Range:** Operates from 4.5V to 12V.  
- **High Output Drive Capability:** ±1A peak output current.  
- **Precision Reference:** Internal 5V reference with ±1% accuracy.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low-voltage conditions.  
- **Soft-Start Capability:** Reduces inrush current during startup.  
- **Synchronization Input:** Allows external clock synchronization.  
- **Current-Limiting Protection:** Enhances system reliability.  

This information is based solely on UNITRODE's datasheet for the UCC3800D.
