Description and Introduction

Digitally Assisted Push Pull PWM Controller 16-HTSSOP -40 to 105 The UCD8220PWP is a synchronous buck controller manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 18V  
- **Output Voltage Range:** Adjustable down to 0.7V  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Maximum Duty Cycle:** 100%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** 20-pin HTSSOP (PWP)  

### **Descriptions:**  
The UCD8220PWP is a high-performance, synchronous buck controller designed for DC/DC power conversion applications. It supports adaptive on-time control for fast transient response and operates in either forced-PWM or diode-emulation mode for improved efficiency at light loads.  

### **Features:**  
- **Adaptive On-Time Control:** Enables fast transient response.  
- **Adjustable Switching Frequency:** 300kHz to 1MHz.  
- **Programmable Soft-Start:** Reduces inrush current.  
- **Power Good Indicator:** Monitors output voltage status.  
- **Overcurrent Protection (OCP):** Prevents damage from excessive current.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Synchronous Rectification:** Improves efficiency.  
- **Diode Emulation Mode:** Enhances light-load efficiency.  

This controller is commonly used in point-of-load (POL) power supplies, telecom, and industrial applications.
