Description and Introduction

Dual Output Synchronous Buck Controller with Wide Input Voltage Range The TPS5602IDBTR is a DC-DC converter manufactured by Texas Instruments (TI). Here are its specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 4.5V to 17V  
- **Output Voltage Range:** 0.8V to 6V (adjustable)  
- **Output Current:** Up to 600mA  
- **Switching Frequency:** 1.6MHz (typical)  
- **Efficiency:** Up to 95%  
- **Operating Temperature Range:** -40°C to +125°C  
- **Package:** DBV (SOT-23-6)  

### **Descriptions:**
- The TPS5602IDBTR is a synchronous step-down (buck) converter with integrated high-side and low-side MOSFETs.  
- It is designed for small, low-power applications requiring high efficiency and compact size.  
- The device operates in pulse-width modulation (PWM) mode and includes features like thermal shutdown and overcurrent protection.  

### **Features:**
- **Integrated MOSFETs:** Reduces external component count.  
- **Fixed-Frequency PWM Operation:** Ensures predictable noise performance.  
- **Adjustable Output Voltage:** Set via external resistors.  
- **Thermal Shutdown Protection:** Prevents damage from overheating.  
- **Overcurrent Protection:** Safeguards against excessive load conditions.  
- **Low Quiescent Current:** Improves efficiency at light loads.  
- **Small Form Factor:** SOT-23-6 package for space-constrained applications.  

This information is sourced from the TI datasheet for the TPS5602IDBTR.

Application Scenarios & Design Considerations

Dual Output Synchronous Buck Controller with Wide Input Voltage Range

Alternative Part Number

  • LM26480SQX --: Dual-channel step-down DC-DC converter with similar input range and current capability, different series naming, suitable as a functional substitute in many power designs.
  • TPS54295PWPR --: Dual synchronous buck converter with comparable voltage and current ratings, different prefix/series, good drop-in candidate for dual-rail supplies.
  • ISL8502IRZ --: Dual-channel buck controller from a different manufacturer and series, offering similar dual-output regulation for cross-reference replacement.
