Description and Introduction

Adjustable, 300-mA, 95% Efficient Step-Down Converter in SOT-23 The TPS62200DBVRG4 is a step-down DC-DC converter manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 2.5V to 6V  
- **Output Voltage Range:** Adjustable (0.7V to VIN)  
- **Output Current:** Up to 300mA  
- **Switching Frequency:** 1.25MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 15µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions:**  
- A synchronous step-down converter with high efficiency and low quiescent current.  
- Designed for battery-powered portable applications.  
- Operates in PWM mode at higher loads and automatically switches to PFM mode at light loads for improved efficiency.  

### **Features:**  
- **Synchronous Rectification:** Improves efficiency and reduces external component count.  
- **100% Duty Cycle Mode:** Allows lowest dropout voltage.  
- **Power-Save Mode:** Enhances light-load efficiency.  
- **Internal Soft-Start:** Limits inrush current.  
- **Undervoltage Lockout (UVLO):** Ensures proper operation under low input voltage conditions.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  

This device is commonly used in portable electronics, IoT devices, and other low-power applications requiring efficient voltage conversion.

Application Scenarios & Design Considerations

Adjustable, 300-mA, 95% Efficient Step-Down Converter in SOT-23

Alternative Part Number

  • TPS62200DBVT --: Same TPS62200 buck converter family in the same SOT-23-5 package, differing only in packing (tape vs reel), so it is a near drop-in replacement.
  • TPS62203DBVR --: Pin-compatible member of the TPS6220x family with the same package and pinout, offering a fixed output variant that can substitute in many designs.
  • AP3402KTR-G1 --: Alternative 2A synchronous step-down converter in a comparable SOT-23-5 footprint, suitable as a cross-vendor replacement for the TPS62200.
  • TPS62200DBVR --: Same TPS62200 step-down converter in the same SOT-23-5 package without the G4 lead-free suffix; functionally identical and widely available.
  • TPS62202DBVR --: Same TPS6220x family in SOT-23-5 with fixed 1.8V output; pin-compatible alternative when a 1.8V output is needed.
