Description and Introduction

Adjustable, up to 3A, 95% Efficient Step-Down Controller, 20uA, SOT-23 The TPS64201DBVR is a step-down (buck) DC/DC converter manufactured by Texas Instruments (TI). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.5 V to 6.5 V  
- **Output Voltage Range:** Adjustable from 0.6 V to VIN  
- **Output Current:** Up to 1.2 A  
- **Switching Frequency:** 1.5 MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 17 µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
- The TPS64201DBVR is a synchronous step-down converter optimized for low-power applications.  
- It integrates low RDS(on) MOSFETs for high efficiency.  
- Operates in pulse-width modulation (PWM) mode for stable output under load.  
- Includes features like soft-start, thermal shutdown, and overcurrent protection.  

### **Features:**  
- **Low Quiescent Current:** Ideal for battery-powered applications.  
- **Synchronous Rectification:** Improves efficiency.  
- **Fixed Frequency Operation:** Reduces output ripple.  
- **Adjustable Output Voltage:** Via external resistors.  
- **Protection Features:** Overcurrent, thermal shutdown, and undervoltage lockout (UVLO).  
- **Small Footprint:** SOT-23-5 package for space-constrained designs.  

This information is based on TI's official datasheet for the TPS64201DBVR.
