Description and Introduction

DUAL, VOLTAGE MODE, DDR SELECTABLE, SYNCHRONOUS, STEP-DOWN CONTROLLER FOR NOTEBOOK SYSTEM POWER The TPS51020DBTRG4 is a dual-output synchronous buck controller manufactured by Texas Instruments (TI) and Burr-Brown (BB).  

### **Specifications:**  
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** Adjustable down to 0.8V  
- **Switching Frequency:** 300kHz to 2MHz (adjustable)  
- **Number of Outputs:** Dual (2 independent outputs)  
- **Output Current:** Up to 10A per channel (dependent on external components)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** TSSOP-16 (DBT)  

### **Descriptions:**  
- The TPS51020DBTRG4 is a high-efficiency, dual-output synchronous buck controller designed for point-of-load (POL) power supplies.  
- It integrates two PWM controllers with adjustable frequency and supports voltage tracking for sequencing applications.  
- Features include soft-start, overcurrent protection, and thermal shutdown.  

### **Features:**  
- **Dual Independent PWM Controllers**  
- **Adjustable Switching Frequency (300kHz–2MHz)**  
- **Synchronous Rectification**  
- **Programmable Soft-Start**  
- **Overcurrent Protection (OCP)**  
- **Thermal Shutdown Protection**  
- **Adjustable Output Voltage (0.8V to VIN)**  
- **Low Quiescent Current**  
- **TSSOP-16 Package**  

This device is commonly used in networking, telecom, and industrial applications requiring efficient power conversion.
