Description and Introduction

Adjustable, up to 3A, 95% Efficient Step-Down Controller, 20uA, SOT-23 The TPS64200DBVT is a step-down DC-DC converter manufactured by Texas Instruments (TI). Below are its specifications, descriptions, and features based on factual information from Ic-phoenix technical data files:

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 6.5V  
- **Output Voltage Range:** Adjustable from 1.2V to 5.5V  
- **Output Current:** Up to 250mA  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 17µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
The TPS64200DBVT is a high-efficiency, low-quiescent-current buck converter designed for battery-powered applications. It integrates a synchronous rectifier to minimize external components and improve efficiency. The device operates in pulse-frequency modulation (PFM) mode at light loads to maximize efficiency and transitions to pulse-width modulation (PWM) mode at higher loads.  

### **Features:**  
- **Ultra-Low Quiescent Current:** 17µA (typical) for extended battery life.  
- **Synchronous Rectification:** Improves efficiency and reduces power dissipation.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Fixed-Frequency Operation:** 1.2MHz switching frequency minimizes external component size.  
- **Soft-Start:** Reduces inrush current during startup.  
- **Thermal Shutdown & Overcurrent Protection:** Ensures safe operation under fault conditions.  
- **Small Footprint:** SOT-23-5 package saves board space.  

This information is strictly based on TI's official datasheet for the TPS64200DBVT.
