Description and Introduction

Dual Output, Two-Phase Synchronous Buck Controller with Wide Input Voltage Range The TPS5120 is a synchronous buck controller manufactured by Texas Instruments (TI). Below are the factual specifications, descriptions, and features from Ic-phoenix technical data files:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 28V  
- **Output Voltage Range:** 0.7V to 5.5V (adjustable)  
- **Output Current:** Up to 20A (with external MOSFETs)  
- **Switching Frequency:** 300kHz to 1MHz (adjustable)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** 20-pin HTSSOP (PowerPAD™)  

### **Descriptions:**
- The TPS5120 is a high-efficiency synchronous buck controller designed for point-of-load (POL) applications.  
- It supports high-current output by driving external N-channel MOSFETs.  
- The device integrates features such as adjustable soft-start, power-good indication, and overcurrent protection.  
- It is suitable for powering processors, FPGAs, and ASICs in computing and industrial applications.  

### **Features:**
- **Adjustable Output Voltage:** Supports a wide range via external resistor divider.  
- **Adjustable Switching Frequency:** Allows optimization for efficiency and component size.  
- **Pre-Biased Output Startup:** Prevents reverse current during startup.  
- **Power-Good (PG) Indicator:** Monitors output voltage status.  
- **Overcurrent Protection (OCP):** Uses inductor DCR sensing or external resistor sensing.  
- **Thermal Shutdown:** Protects the device from overheating.  
- **Synchronization Capability:** Can sync to an external clock.
