Description and Introduction

Adjustable, up to 3A, 95% Efficient Step-Down Controller, 20uA, SOT-23 The TPS64200DBVR is a step-down DC-DC converter manufactured by Texas Instruments (TI).  

### **Specifications:**  
- **Input Voltage Range:** 2.7V to 6.5V  
- **Output Voltage Range:** Adjustable from 1.2V to 5.5V  
- **Output Current:** Up to 200mA  
- **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 TPS64200DBVR is a synchronous step-down converter optimized for low-power applications. It integrates a high-side P-channel MOSFET and a low-side N-channel MOSFET, providing high efficiency and compact design.  

### **Features:**  
- **Low Quiescent Current:** 17µA (typical) for improved efficiency in light-load conditions.  
- **Synchronous Rectification:** Enhances efficiency by reducing power loss.  
- **Fixed-Frequency PWM Operation:** Ensures predictable noise performance.  
- **Soft-Start Function:** Prevents inrush current during startup.  
- **Thermal Shutdown Protection:** Safeguards the device from overheating.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation within input voltage range.  

This device is suitable for battery-powered applications, portable electronics, and other low-power systems requiring efficient voltage conversion.
