Description and Introduction

CONSTANT CURRENT LED DRIVER WITH DIGITAL AND PWM BRIGHTNESS CONTROL The TPS61061DRB is a boost converter manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**  
- **Input Voltage Range:** 0.9V to 5.5V  
- **Output Voltage Range:** Adjustable from 1.8V to 5.5V  
- **Output Current:** Up to 300mA (depending on input/output conditions)  
- **Switching Frequency:** 1.2MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 19µA (typical)  
- **Shutdown Current:** <1µA  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SON-6 (DRB)  

### **Descriptions:**  
The TPS61061DRB is a high-efficiency, low-quiescent-current boost converter designed for battery-powered applications. It integrates a synchronous rectifier to improve efficiency and supports a wide input voltage range, making it suitable for single-cell or multi-cell battery systems.  

### **Features:**  
- **True Disconnect in Shutdown Mode** – Prevents battery drain when disabled.  
- **Automatic Transition Between PWM and PFM Modes** – Optimizes efficiency across load conditions.  
- **Integrated Synchronous Rectifier** – Eliminates the need for an external Schottky diode.  
- **Low Start-up Voltage (0.9V)** – Supports weak battery conditions.  
- **Thermal Shutdown and Overcurrent Protection** – Enhances reliability.  
- **Small Footprint (SON-6 Package)** – Suitable for space-constrained designs.  

This information is based solely on the manufacturer's datasheet.

Application Scenarios & Design Considerations

CONSTANT CURRENT LED DRIVER WITH DIGITAL AND PWM BRIGHTNESS CONTROL

Alternative Part Number

  • TPS61060DRB --: Same TPS6106x boost converter family in the same DRB package, differing only in output voltage option, so it is a near drop-in replacement with identical pinout and function.
  • TPS61062DRB --: Another member of the same TPS6106x series in the identical DRB package, offering a different fixed output voltage but the same topology and pin configuration.
  • LTC3525ESC6 --: Comparable low-voltage boost converter from a different vendor and series, suitable as a functional cross when the exact TI variant is unavailable, though pinout and package must be verified.
