Description and Introduction

Q1 The TPS61041DBVRG4 is a boost converter from Texas Instruments (TI). Here are the factual details from Ic-phoenix technical data files:

### **Specifications:**
- **Manufacturer:** Texas Instruments (TI)  
- **Part Number:** TPS61041DBVRG4  
- **Type:** Boost (Step-Up) DC-DC Converter  
- **Input Voltage Range:** 0.9V to 5.5V  
- **Output Voltage Range:** Adjustable (up to 5.5V)  
- **Output Current:** Up to 250mA (depends on input/output conditions)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5 (DBV)  

### **Descriptions and Features:**
- **Ultra-Low Start-Up Voltage:** Can start with input voltages as low as 0.9V.  
- **High Efficiency:** Optimized for low-power applications.  
- **Fixed and Adjustable Output Voltage Options:** Supports adjustable output via external resistors.  
- **Integrated Power Switch:** Simplifies design and reduces external components.  
- **Low Quiescent Current:** Typically 19µA for improved battery life.  
- **Over-Temperature Protection:** Includes thermal shutdown.  
- **Soft-Start Function:** Reduces inrush current during startup.  

This information is strictly based on the manufacturer's datasheet and technical documentation.

Application Scenarios & Design Considerations

Q1

Alternative Part Number

  • TPS61041DBVR --: Same TPS61041 boost converter in the same SOT-23-5 package, identical electrical specifications; the G4 suffix only denotes lead-free/RoHS green packaging, so this is a direct drop-in replacement.
  • TPS61040DBVR --: Same TPS6104x family boost converter in the same SOT-23-5 package with nearly identical specifications; the main difference is the feedback reference voltage, so verify the output voltage setting before use.
  • AP3015AKTR-G1 --: Alternative boost converter in a comparable SOT-23-5 package with similar input voltage and switching current ratings; requires checking feedback voltage and pinout compatibility.
  • AP3012KTR-G1 --: Pin-compatible boost converter in SOT-23-5 from a different vendor, suitable as a second-source alternative when TI parts are unavailable.
