Description and Introduction

1.2A High Power White LED Driver with I2C Compatible Interface 12-DSBGA -40 to 85 The TPS61050YZGR is a high-efficiency, low-noise boost converter manufactured by Texas Instruments (TI). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 1.8 V to 5.5 V  
- **Output Voltage Range:** Adjustable from 2.5 V to 5.5 V (fixed 3.3 V or 5 V options available)  
- **Output Current:** Up to 300 mA (depending on input/output conditions)  
- **Switching Frequency:** 1 MHz (typical)  
- **Efficiency:** Up to 95%  
- **Quiescent Current:** 19 µA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** DSBGA (YZR), 9-pin  

### **Descriptions:**
The TPS61050YZGR is a synchronous boost converter designed for low-power applications. It integrates a power switch and synchronous rectifier to improve efficiency and reduce external component count. The device operates in pulse-frequency modulation (PFM) mode at light loads to maintain high efficiency across a wide load range.

### **Features:**
- **Low Noise:** Optimized for noise-sensitive applications  
- **Automatic PFM/PWM Mode Switching:** Enhances efficiency at light and heavy loads  
- **True Disconnect in Shutdown:** Prevents battery drain when disabled  
- **Soft-Start:** Reduces inrush current  
- **Overcurrent and Overtemperature Protection:** Ensures safe operation  
- **Small Footprint:** Suitable for space-constrained designs  

This device is commonly used in portable electronics, battery-powered systems, and IoT applications.
